The present invention was made with support from the Government under Agreement No. HR0011-11-3-0001 awarded by DARPA. The Government has certain rights in the invention.

The invention relates to artificial nucleic acid molecules comprising an open reading frame, a 3′-untranslated region element (3′-UTR element) and optionally a poly(A) sequence and/or a polyadenylation-signal. The invention relates further to a vector comprising a 3′-UTR element, to a cell comprising the artificial nucleic acid molecule or the vector, to a pharmaceutical composition comprising the artificial nucleic acid molecule or the vector and to a kit comprising the artificial nucleic acid molecule, the vector and/or the pharmaceutical composition, preferably for use in the field of gene therapy and/or genetic vaccination.

Gene therapy and genetic vaccination belong to the most promising and quickly developing methods of modern medicine. They may provide highly specific and individual options for therapy of a large variety of diseases. Particularly, inherited genetic diseases but also autoimmune diseases, cancerous or tumour-related diseases as well as inflammatory diseases may be the subject of such treatment approaches. Also, it is envisaged to prevent early onset of such diseases by these approaches.

The main conceptual rational behind gene therapy is appropriate modulation of impaired gene expression associated with pathological conditions of specific diseases. Pathologically altered gene expression may result in lack or overproduction of essential gene products, for example, signalling factors such as hormones, housekeeping factors, metabolic enzymes, structural proteins or the like. Altered gene expression may not only be due to mis-regulation of transcription and/or translation, but also due to mutations within the ORF coding for a particular protein. Pathological mutations may be caused by e.g. chromosomal aberration, or by more specific mutations, such as point or frame-shift-mutations, all of them resulting in limited functionality and, potentially, total loss of function of the gene product. However, misregulation of transcription or translation may also occur, if mutations affect genes encoding proteins which are involved in the transcriptional or translational machinery of the cell. Such mutations may lead to pathological up- or down-regulation of genes which are—as such—functional. Genes encoding gene products which exert such regulating functions, may be, e.g., transcription factors, signal receptors, messenger proteins or the like. However, loss of function of such genes encoding regulatory proteins may, under certain circumstances, be reversed by artificial introduction of other factors acting further downstream of the impaired gene product. Such gene defects may also be compensated by gene therapy via substitution of the affected gene itself.

Genetic vaccination allows evoking a desired immune response to selected antigens, such as characteristic components of bacterial surfaces, viral particles, tumour antigens or the like. Generally, vaccination is one of the pivotal achievements of modern medicine. However, effective vaccines are currently available only for a limited number of diseases. Accordingly, infections that are not preventable by vaccination still affect millions of people every year.

Commonly, vaccines may be subdivided into “first”, “second” and “third” generation vaccines. “First generation” vaccines are, typically, whole-organism vaccines. They are based on either live and attenuated or killed pathogens, e.g. viruses, bacteria or the like. The major drawback of live and attenuated vaccines is the risk for a reversion to life-threatening variants. Thus, although attenuated, such pathogens may still intrinsically bear unpredictable risks. Killed pathogens may not be as effective as desired for generating a specific immune response. In order to minimize these risks, “second generation” vaccines were developed. These are, typically, subunit vaccines, consisting of defined antigens or recombinant protein components which are derived from pathogens.

Genetic vaccines, i.e. vaccines for genetic vaccination, are usually understood as “third generation” vaccines. They are typically composed of genetically engineered nucleic acid molecules which allow expression of peptide or protein (antigen) fragments characteristic for a pathogen or a tumor antigen in vivo. Genetic vaccines are expressed upon administration to a patient after uptake by target cells. Expression of the administered nucleic acids results in production of the encoded proteins. In the event these proteins are recognized as foreign by the patient's immune system, an immune response is triggered.

As can be seen from the above, both methods, gene therapy and genetic vaccination, are essentially based on the administration of nucleic acid molecules to a patient and subsequent transcription and/or translation of the encoded genetic information. Alternatively, genetic vaccination or gene therapy may also comprise methods which include isolation of specific body cells from a patient to be treated, subsequent ex vivo transfection of such cells, and re-administration of the treated cells to the patient.

DNA as well as RNA may be used as nucleic acid molecules for administration in the context of gene therapy or genetic vaccination. DNA is known to be relatively stable and easy to handle. However, the use of DNA bears the risk of undesired insertion of the administered DNA-fragments into the patient's genome potentially resulting mutagenic events such as in loss of function of the impaired genes. As a further risk, the undesired generation of anti-DNA antibodies has emerged. Another drawback is the limited expression level of the encoded peptide or protein that is achievable upon DNA administration because the DNA must enter the nucleus in order to be transcribed before the resulting mRNA can be translated. Among other reasons, the expression level of the administered DNA will be dependent on the presence of specific transcription factors which regulate DNA transcription. In the absence of such factors, DNA transcription will not yield satisfying amounts of RNA. As a result, the level of translated peptide or protein obtained is limited.

By using RNA instead of DNA for gene therapy or genetic vaccination, the risk of undesired genomic integration and generation of anti-DNA antibodies is minimized or avoided. However, RNA is considered to be a rather unstable molecular species which may readily be degraded by ubiquitous RNAses.

In vivo, RNA degradation contributes to the regulation of the RNA half-life time. That effect was considered and proven to fine tune the regulation of eukaryotic gene expression (Friedel et al., 2009. Conserved principles of mammalian transcriptional regulation revealed by RNA half-life, Nucleic Acid Research 37(17): 1-12). Accordingly, each naturally occurring mRNA has its individual half-life depending on the gene from which the mRNA is derived and in which cell type it is expressed. It contributes to the regulation of the expression level of this gene. Unstable RNAs are important to realize transient gene expression at distinct points in time. However, long-lived RNAs may be associated with accumulation of distinct proteins or continuous expression of genes. In vivo, the half-life of mRNAs may also be dependent on environmental factors, such as hormonal treatment, as has been shown, e.g., for insulin-like growth factor I, actin, and albumin mRNA (Johnson et al., Newly synthesized RNA: Simultaneous measurement in intact cells of transcription rates and RNA stability of insulin-like growth factor I, actin, and albumin in growth hormone-stimulated hepatocytes, Proc. Natl. Acad. Sci., Vol. 88, pp. 5287-5291, 1991).

For gene therapy and genetic vaccination, usually stable RNA is desired. This is, on the one hand, due to the fact that it is usually desired that the product encoded by the RNA sequence accumulates in vivo. On the other hand, the RNA has to maintain its structural and functional integrity when prepared for a suitable dosage form, in the course of its storage, and when administered. Thus, efforts were made to provide stable RNA molecules for gene therapy or genetic vaccination in order to prevent them from being subject to early degradation or decay.

It has been reported that the G/C-content of nucleic acid molecules may influence their stability. Thus, nucleic acids comprising an increased amount of guanine (G) and/or cytosine (C) residues may be functionally more stable than nucleic acids containing a large amount of adenine (A) and thymine (T) or uracil (U) nucleotides. In this context, WO02/098443 provides a pharmaceutical composition containing an mRNA that is stabilised by sequence modifications in the coding region. Such a sequence modification takes advantage of the degeneracy of the genetic code. Accordingly, codons which contain a less favourable combination of nucleotides (less favourable in terms of RNA stability) may be substituted by alternative codons without altering the encoded amino acid sequence. This method of RNA stabilization is limited by the provisions of the specific nucleotide sequence of each single RNA molecule which is not allowed to leave the space of the desired amino acid sequence. Also, that approach is restricted to coding regions of the RNA.

As an alternative option for mRNA stabilisation, it has been found that naturally occurring eukaryotic mRNA molecules contain characteristic stabilising elements. For example, they may comprise so-called untranslated regions (UTR) at their 5′-end (5′-UTR) and/or at their 3′-end (3′-UTR) as well as other structural features, such as a 5′-cap structure or a 3′-poly(A) tail. Both, 5′-UTR and 3′-UTR are typically transcribed from the genomic DNA and are, thus, an element of the premature mRNA. Characteristic structural features of mature mRNA, such as the 5′-cap and the 3′-poly(A) tail (also called poly(A) tail or poly(A) sequence) are usually added to the transcribed (premature) mRNA during mRNA processing.

A 3′-poly(A) tail is typically a monotonous sequence stretch of adenosine nucleotides added to the 3′-end of the transcribed mRNA. It may comprise up to about 400 adenosine nucleotides. It was found that the length of such a 3′-poly(A) tail is a potentially critical element for the stability of the individual mRNA.

Also, it was shown that the 3′-UTR of α-globin mRNA may be an important factor for the well-known stability of α-globin mRNA (Rodgers et al., Regulated α-globin mRNA decay is a cytoplasmic event proceeding through 3′-to-5′ exosome-dependent decapping, RNA, 8, pp. 1526-1537, 2002). The 3′-UTR of α-globin mRNA is apparently involved in the formation of a specific ribonucleoprotein-complex, the α-complex, whose presence correlates with mRNA stability in vitro (Wang et al., An mRNA stability complex functions with poly(A)-binding protein to stabilize mRNA in vitro, Molecular and Cellular biology, Vol 19, No. 7, July 1999, p. 4552-4560).

An interesting regulatory function has further been demonstrated for the UTRs in ribosomal protein mRNAs: while the 5′-UTR of ribosomal protein mRNAs controls the growth-associated translation of the mRNA, the stringency of that regulation is conferred by the respective 3′-UTR in ribosomal protein mRNAs (Ledda et al., Effect of the 3′-UTR length on the translational regulation of 5′-terminal oligopyrimidine mRNAs, Gene, Vol. 344, 2005, p. 213-220). This mechanism contributes to the specific expression pattern of ribosomal proteins, which are typically transcribed in a constant manner so that some ribosomal protein mRNAs such as ribosomal protein S9 or ribosomal protein L32 are referred to as housekeeping genes (Janovick-Guretzky et al., Housekeeping Gene Expression in Bovine Liver is Affected by Physiological State, Feed Intake, and Dietary Treatment, J. Dairy Sci., Vol. 90, 2007, p. 2246-2252). The growth-associated expression pattern of ribosomal proteins is thus mainly due to regulation on the level of translation.

Irrespective of factors influencing mRNA stability, effective translation of the administered nucleic acid molecules by the target cells or tissue is crucial for any approach using nucleic acid molecules for gene therapy or genetic vaccination. As can be seen from the examples cited above, along with the regulation of stability, also translation of the majority of mRNAs is regulated by structural features like UTRs, 5′-cap and 3′-poly(A) tail. In this context, it has been reported that the length of the poly(A) tail may play an important role for translational efficiency as well. Stabilizing 3′-elements, however, may also have an attenuating effect on translation.

It is the object of the invention to provide nucleic acid molecules, which may be suitable for application in gene therapy and/or genetic vaccination. Particularly, it is the object of the invention to provide an mRNA species, which is stabilized against preterm degradation or decay without exhibiting significant functional loss in translational efficiency. It is also an object of the invention to provide an artificial nucleic acid molecule, preferably an mRNA, which is characterized by enhanced expression of the respective protein encoded by said nucleic acid molecule. One particular object of the invention is the provision of an mRNA, wherein the efficiency of translation of the respective encoded protein is enhanced. Another object of the present invention is to provide nucleic acid molecules coding for such a superior mRNA species, which may be amenable for use in gene therapy and/or genetic vaccination. It is a further object of the present invention to provide a pharmaceutical composition for use in gene therapy and/or genetic vaccination. In summary, it is the object of the present invention to provide improved nucleic acid species which overcome the above discussed disadvantages of the prior art by a cost-effective and straight-forward approach.

The object underlying the present invention is solved by the claimed subject matter.

For the sake of clarity and readability the following definitions are provided. Any technical feature mentioned for these definitions may be read on each and every embodiment of the invention. Additional definitions and explanations may be specifically provided in the context of these embodiments.

Adaptive immune response: The adaptive immune response is typically understood to be an antigen-specific response of the immune system. Antigen specificity allows for the generation of responses that are tailored to specific pathogens or pathogen-infected cells. The ability to mount these tailored responses is usually maintained in the body by “memory cells”. Should a pathogen infect the body more than once, these specific memory cells are used to quickly eliminate it. In this context, the first step of an adaptive immune response is the activation of naïve antigen-specific T cells or different immune cells able to induce an antigen-specific immune response by antigen-presenting cells. This occurs in the lymphoid tissues and organs through which naïve T cells are constantly passing. The three cell types that may serve as antigen-presenting cells are dendritic cells, macrophages, and B cells. Each of these cells has a distinct function in eliciting immune responses. Dendritic cells may take up antigens by phagocytosis and macropinocytosis and may become stimulated by contact with e.g. a foreign antigen to migrate to the local lymphoid tissue, where they differentiate into mature dendritic cells. Macrophages ingest particulate antigens such as bacteria and are induced by infectious agents or other appropriate stimuli to express MHC molecules. The unique ability of B cells to bind and internalize soluble protein antigens via their receptors may also be important to induce T cells. MHC-molecules are, typically, responsible for presentation of an antigen to T-cells. Therein, presenting the antigen on MHC molecules leads to activation of T cells, which induces their proliferation and differentiation into armed effector T cells. The most important function of effector T cells is the killing of infected cells by CD8+ cytotoxic T cells and the activation of macrophages by Th1 cells, which together make up cell-mediated immunity, and the activation of B cells by both Th2 and Th1 cells to produce different classes of antibody, thus driving the humoral immune response. T cells recognize an antigen by their T cell receptors which do not recognize and bind the antigen directly, but instead recognize short peptide fragments e.g. of pathogen-derived protein antigens, e.g. so-called epitopes, which are bound to MHC molecules on the surfaces of other cells.

Adaptive immune system: The adaptive immune system is essentially dedicated to eliminate or prevent pathogenic growth. It typically regulates the adaptive immune response by providing the vertebrate immune system with the ability to recognize and remember specific pathogens (to generate immunity), and to mount stronger attacks each time the pathogen is encountered. The system is highly adaptable because of somatic hypermutation (a process of accelerated somatic mutations), and V(D)J recombination (an irreversible genetic recombination of antigen receptor gene segments). This mechanism allows a small number of genes to generate a vast number of different antigen receptors, which are then uniquely expressed on each individual lymphocyte. Because the gene rearrangement leads to an irreversible change in the DNA of each cell, all of the progeny (offspring) of such a cell will then inherit genes encoding the same receptor specificity, including the Memory B cells and Memory T cells that are the keys to long-lived specific immunity.

Adjuvant/adjuvant component: An adjuvant or an adjuvant component in the broadest sense is typically a pharmacological and/or immunological agent that may modify, e.g. enhance, the effect of other agents, such as a drug or vaccine. It is to be interpreted in a broad sense and refers to a broad spectrum of substances. Typically, these substances are able to increase the immunogenicity of antigens. For example, adjuvants may be recognized by the innate immune systems and, e.g., may elicit an innate immune response. “Adjuvants” typically do not elicit an adaptive immune response. Insofar, “adjuvants” do not qualify as antigens. Their mode of action is distinct from the effects triggered by antigens resulting in an adaptive immune response.

Antigen: In the context of the present invention “antigen” refers typically to a substance which may be recognized by the immune system, preferably by the adaptive immune system, and is capable of triggering an antigen-specific immune response, e.g. by formation of antibodies and/or antigen-specific T cells as part of an adaptive immune response. Typically, an antigen may be or may comprise a peptide or protein, which may be presented by the MHC to T-cells. In the sense of the present invention an antigen may be the product of translation of a provided nucleic acid molecule, preferably an mRNA as defined herein. In this context, also fragments, variants and derivatives of peptides and proteins comprising at least one epitope are understood as antigens. In the context of the present invention, tumour antigens and pathogenic antigens as defined herein are particularly preferred.

Artificial nucleic acid molecule: An artificial nucleic acid molecule may typically be understood to be a nucleic acid molecule, e.g. a DNA or an RNA, that does not occur naturally. In other words, an artificial nucleic acid molecule may be understood as a non-natural nucleic acid molecule. Such nucleic acid molecule may be non-natural due to its individual sequence (which does not occur naturally) and/or due to other modifications, e.g. structural modifications of nucleotides, which do not occur naturally. An artificial nucleic acid molecule may be a DNA molecule, an RNA molecule or a hybrid-molecule comprising DNA and RNA portions. Typically, artificial nucleic acid molecules may be designed and/or generated by genetic engineering methods to correspond to a desired artificial sequence of nucleotides (heterologous sequence). In this context an artificial sequence is usually a sequence that may not occur naturally, i.e. it differs from the wild type sequence by at least one nucleotide. The term “wild type” may be understood as a sequence occurring in nature. Further, the term “artificial nucleic acid molecule” is not restricted to mean “one single molecule” but is, typically, understood to comprise an ensemble of identical molecules. Accordingly, it may relate to a plurality of identical molecules contained in an aliquot.

Bicistronic RNA, multicistronic RNA: A bicistronic or multicistronic RNA is typically an RNA, preferably an mRNA, that typically may have two (bicistronic) or more (multicistronic) open reading frames (ORF). An open reading frame in this context is a sequence of codons that is translatable into a peptide or protein.

Carrier/polymeric carrier: A carrier in the context of the invention may typically be a compound that facilitates transport and/or complexation of another compound (cargo). A polymeric carrier is typically a carrier that is formed of a polymer. A carrier may be associated to its cargo by covalent or non-covalent interaction. A carrier may transport nucleic acids, e.g. RNA or DNA, to the target cells. The carrier may—for some embodiments—be a cationic component.

Cationic component: The term “cationic component” typically refers to a charged molecule, which is positively charged (cation) at a pH value typically from 1 to 9, preferably at a pH value of or below 9 (e.g. from 5 to 9), of or below 8 (e.g. from 5 to 8), of or below 7 (e.g. from 5 to 7), most preferably at a physiological pH, e.g. from 7.3 to 7.4. Accordingly, a cationic component may be any positively charged compound or polymer, preferably a cationic peptide or protein, which is positively charged under physiological conditions, particularly under physiological conditions in vivo. A “cationic peptide or protein” may contain at least one positively charged amino acid, or more than one positively charged amino acid, e.g. selected from Arg, His, Lys or Orn. Accordingly, “polycationic” components are also within the scope exhibiting more than one positive charge under the conditions given.

5′-cap: A 5′-cap is an entity, typically a modified nucleotide entity, which generally “caps” the 5′-end of a mature mRNA. A 5′-cap may typically be formed by a modified nucleotide, particularly by a derivative of a guanine nucleotide. Preferably, the 5′-cap is linked to the 5′-terminus via a 5′-5′-triphosphate linkage. A 5′-cap may be methylated, e.g. m7GpppN, wherein N is the terminal 5′ nucleotide of the nucleic acid carrying the 5′-cap, typically the 5′-end of an RNA. Further examples of 5′cap structures include glyceryl, inverted deoxy abasic residue (moiety), 4′,5′ methylene nucleotide, 1-(beta-D-erythrofuranosyl) nucleotide, 4′-thio nucleotide, carbocyclic nucleotide, 1,5-anhydrohexitol nucleotide, L-nucleotides, alpha-nucleotide, modified base nucleotide, threo-pentofuranosyl nucleotide, acyclic 3′,4′-seco nucleotide, acyclic 3,4-dihydroxybutyl nucleotide, acyclic 3,5 dihydroxypentyl nucleotide, 3′-3′-inverted nucleotide moiety, 3′-3′-inverted abasic moiety, 3′-2′-inverted nucleotide moiety, 3′-2′-inverted abasic moiety, 1,4-butanediol phosphate, 3′-phosphoramidate, hexylphosphate, aminohexyl phosphate, 3′-phosphate, 3′phosphorothioate, phosphorodithioate, or bridging or non-bridging methylphosphonate moiety.

Cellular immunity/cellular immune response: Cellular immunity relates typically to the activation of macrophages, natural killer cells (NK), antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen. In more general terms, cellular immunity is not based on antibodies, but on the activation of cells of the immune system. Typically, a cellular immune response may be characterized e.g. by activating antigen-specific cytotoxic T-lymphocytes that are able to induce apoptosis in cells, e.g. specific immune cells like dendritic cells or other cells, displaying epitopes of foreign antigens on their surface. Such cells may be virus-infected or infected with intracellular bacteria, or cancer cells displaying tumor antigens. Further characteristics may be activation of macrophages and natural killer cells, enabling them to destroy pathogens and stimulation of cells to secrete a variety of cytokines that influence the function of other cells involved in adaptive immune responses and innate immune responses.

DNA: DNA is the usual abbreviation for deoxy-ribonucleic acid. It is a nucleic acid molecule, i.e. a polymer consisting of nucleotides. These nucleotides are usually deoxy-adenosine-monophosphate, deoxy-thymidine-monophosphate, deoxy-guanosine-monophosphate and deoxy-cytidine-monophosphate monomers which are—by themselves—composed of a sugar moiety (deoxyribose), a base moiety and a phosphate moiety, and polymerise by a characteristic backbone structure. The backbone structure is, typically, formed by phosphodiester bonds between the sugar moiety of the nucleotide, i.e. deoxyribose, of a first and a phosphate moiety of a second, adjacent monomer. The specific order of the monomers, i.e. the order of the bases linked to the sugar/phosphate-backbone, is called the DNA sequence. DNA may be single stranded or double stranded. In the double stranded form, the nucleotides of the first strand typically hybridize with the nucleotides of the second strand, e.g. by A/T-base-pairing and G/C-base-pairing.

Epitope: (also called “antigen determinant”) can be distinguished in T cell epitopes and B cell epitopes. T cell epitopes or parts of the proteins in the context of the present invention may comprise fragments preferably having a length of about 6 to about 20 or even more amino acids, e.g. fragments as processed and presented by MHC class I molecules, preferably having a length of about 8 to about 10 amino acids, e.g. 8, 9, or 10, (or even 11, or 12 amino acids), or fragments as processed and presented by MHC class II molecules, preferably having a length of about 13 or more amino acids, e.g. 13, 14, 15, 16, 17, 18, 19, 20 or even more amino acids, wherein these fragments may be selected from any part of the amino acid sequence. These fragments are typically recognized by T cells in form of a complex consisting of the peptide fragment and an MHC molecule, i.e. the fragments are typically not recognized in their native form. B cell epitopes are typically fragments located on the outer surface of (native) protein or peptide antigens as defined herein, preferably having 5 to 15 amino acids, more preferably having 5 to 12 amino acids, even more preferably having 6 to 9 amino acids, which may be recognized by antibodies, i.e. in their native form.

Such epitopes of proteins or peptides may furthermore be selected from any of the herein mentioned variants of such proteins or peptides. In this context antigenic determinants can be conformational or discontinuous epitopes which are composed of segments of the proteins or peptides as defined herein that are discontinuous in the amino acid sequence of the proteins or peptides as defined herein but are brought together in the three-dimensional structure or continuous or linear epitopes which are composed of a single polypeptide chain.

Fragment of a sequence: A fragment of a sequence may typically be a shorter portion of a full-length sequence of e.g. a nucleic acid molecule or an amino acid sequence. Accordingly, a fragment, typically, consists of a sequence that is identical to the corresponding stretch within the full-length sequence. A preferred fragment of a sequence in the context of the present invention, consists of a continuous stretch of entities, such as nucleotides or amino acids corresponding to a continuous stretch of entities in the molecule the fragment is derived from, which represents at least 5%, 10%, 20%, preferably at least 30%, more preferably at least 40%, more preferably at least 50%, even more preferably at least 60%, even more preferably at least 70%, and most preferably at least 80% of the total (i.e. full-length) molecule from which the fragment is derived.

G/C modified: A G/C-modified nucleic acid may typically be a nucleic acid, preferably an artificial nucleic acid molecule as defined herein, based on a modified wild-type sequence comprising a preferably increased number of guanosine and/or cytosine nucleotides as compared to the wild-type sequence. Such an increased number may be generated by substitution of codons containing adenosine or thymidine nucleotides by codons containing guanosine or cytosine nucleotides. If the enriched G/C content occurs in a coding region of DNA or RNA, it makes use of the degeneracy of the genetic code. Accordingly, the codon substitutions preferably do not alter the encoded amino acid residues, but exclusively increase the G/C content of the nucleic acid molecule.

Gene therapy: Gene therapy may typically be understood to mean a treatment of a patient's body or isolated elements of a patient's body, for example isolated tissues/cells, by nucleic acids encoding a peptide or protein. It typically may comprise at least one of the steps of a) administration of a nucleic acid, preferably an artificial nucleic acid molecule as defined herein, directly to the patient—by whatever administration route—or in vitro to isolated cells/tissues of the patient, which results in transfection of the patient's cells either in vivo/ex vivo or in vitro; b) transcription and/or translation of the introduced nucleic acid molecule; and optionally c) re-administration of isolated, transfected cells to the patient, if the nucleic acid has not been administered directly to the patient.

Genetic vaccination: Genetic vaccination may typically be understood to be vaccination by administration of a nucleic acid molecule encoding an antigen or an immunogen or fragments thereof. The nucleic acid molecule may be administered to a subject's body or to isolated cells of a subject. Upon transfection of certain cells of the body or upon transfection of the isolated cells, the antigen or immunogen may be expressed by those cells and subsequently presented to the immune system, eliciting an adaptive, i.e. antigen-specific immune response. Accordingly, genetic vaccination typically comprises at least one of the steps of a) administration of a nucleic acid, preferably an artificial nucleic acid molecule as defined herein, to a subject, preferably a patient, or to isolated cells of a subject, preferably a patient, which usually results in transfection of the subject's cells either in vivo or in vitro; b) transcription and/or translation of the introduced nucleic acid molecule; and optionally c) re-administration of isolated, transfected cells to the subject, preferably the patient, if the nucleic acid has not been administered directly to the patient.

Heterologous sequence: Two sequences are typically understood to be ‘heterologous’ if they are not derivable from the same gene. I.e., although heterologous sequences may be derivable from the same organism, they naturally (in nature) do not occur in the same nucleic acid molecule, such as in the same mRNA.

Humoral immunity/humoral immune response: Humoral immunity refers typically to antibody production and optionally to accessory processes accompanying antibody production. A humoral immune response may be typically characterized, e.g., by Th2 activation and cytokine production, germinal center formation and isotype switching, affinity maturation and memory cell generation. Humoral immunity also typically may refer to the effector functions of antibodies, which include pathogen and toxin neutralization, classical complement activation, and opsonin promotion of phagocytosis and pathogen elimination.

Immunogen: In the context of the present invention, an immunogen may be typically understood to be a compound that is able to stimulate an immune response. Preferably, an immunogen is a peptide, polypeptide, or protein. In a particularly preferred embodiment, an immunogen in the sense of the present invention is the product of translation of a provided nucleic acid molecule, preferably an artificial nucleic acid molecule as defined herein. Typically, an immunogen elicits at least an adaptive immune response.

Immunostimulatory composition: In the context of the invention, an immunostimulatory composition may be typically understood to be a composition containing at least one component which is able to induce an immune response or from which a component, which is able to induce an immune response, is derivable. Such immune response may be preferably an innate immune response or a combination of an adaptive and an innate immune response. Preferably, an immunostimulatory composition in the context of the invention contains at least one artificial nucleic acid molecule, more preferably an RNA, for example an mRNA molecule. The immunostimulatory component, such as the mRNA may be complexed with a suitable carrier. Thus, the immunostimulatory composition may comprise an mRNA/carrier-complex. Furthermore, the immunostimulatory composition may comprise an adjuvant and/or a suitable vehicle for the immunostimulatory component, such as the mRNA.

Immune response: An immune response may typically be a specific reaction of the adaptive immune system to a particular antigen (so called specific or adaptive immune response) or an unspecific reaction of the innate immune system (so called unspecific or innate immune response), or a combination thereof.

Immune system: The immune system may protect organisms from infection. If a pathogen succeeds in passing a physical barrier of an organism and enters this organism, the innate immune system provides an immediate, but non-specific response. If pathogens evade this innate response, vertebrates possess a second layer of protection, the adaptive immune system. Here, the immune system adapts its response during an infection to improve its recognition of the pathogen. This improved response is then retained after the pathogen has been eliminated, in the form of an immunological memory, and allows the adaptive immune system to mount faster and stronger attacks each time this pathogen is encountered. According to this, the immune system comprises the innate and the adaptive immune system. Each of these two parts typically contains so called humoral and cellular components.

Immunostimulatory RNA: An immunostimulatory RNA (isRNA) in the context of the invention may typically be an RNA that is able to induce an innate immune response. It usually does not have an open reading frame and thus does not provide a peptide-antigen or immunogen but elicits an immune response e.g. by binding to a specific kind of Toll-like-receptor (TLR) or other suitable receptors. However, of course also mRNAs having an open reading frame and coding for a peptide/protein may induce an innate immune response and, thus, may be immunostimulatory RNAs.

Innate immune system: The innate immune system, also known as non-specific (or unspecific) immune system, typically comprises the cells and mechanisms that defend the host from infection by other organisms in a non-specific manner. This means that the cells of the innate system may recognize and respond to pathogens in a generic way, but unlike the adaptive immune system, it does not confer long-lasting or protective immunity to the host. The innate immune system may be, e.g., activated by ligands of Toll-like receptors (TLRs) or other auxiliary substances such as lipopolysaccharides, TNF-alpha, CD40 ligand, or cytokines, monokines, lymphokines, interleukins or chemokines, IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-11, IL-12, IL-13, IL-14, IL-15, IL-16, IL-17, IL-18, IL-19, IL-20, IL-21, IL-22, IL-23, IL-24, IL-25, IL-26, IL-27, IL-28, IL-29, IL-30, IL-31, IL-32, IL-33, IFN-alpha, IFN-beta, IFN-gamma, GM-CSF, G-CSF, M-CSF, LT-beta, TNF-alpha, growth factors, and hGH, a ligand of human Toll-like receptor TLR1, TLR2, TLR3, TLR4, TLR5, TLR6, TLR7, TLR8, TLR9, TLR10, a ligand of murine Toll-like receptor TLR1, TLR2, TLR3, TLR4, TLR5, TLR6, TLR7, TLR8, TLR9, TLR10, TLR11, TLR12 or TLR13, a ligand of a NOD-like receptor, a ligand of a RIG-I like receptor, an immunostimulatory nucleic acid, an immunostimulatory RNA (isRNA), a CpG-DNA, an antibacterial agent, or an anti-viral agent. The pharmaceutical composition according to the present invention may comprise one or more such substances. Typically, a response of the innate immune system includes recruiting immune cells to sites of infection, through the production of chemical factors, including specialized chemical mediators, called cytokines; activation of the complement cascade; identification and removal of foreign substances present in organs, tissues, the blood and lymph, by specialized white blood cells; activation of the adaptive immune system; and/or acting as a physical and chemical barrier to infectious agents.

Cloning site: A cloning site is typically understood to be a segment of a nucleic acid molecule, which is suitable for insertion of a nucleic acid sequence, e.g., a nucleic acid sequence comprising an open reading frame. Insertion may be performed by any molecular biological method known to the one skilled in the art, e.g. by restriction and ligation. A cloning site typically comprises one or more restriction enzyme recognition sites (restriction sites). These one or more restrictions sites may be recognized by restriction enzymes which cleave the DNA at these sites. A cloning site which comprises more than one restriction site may also be termed a multiple cloning site (MCS) or a polylinker.

Nucleic acid molecule: A nucleic acid molecule is a molecule comprising, preferably consisting of nucleic acid components. The term nucleic acid molecule preferably refers to DNA or RNA molecules. It is preferably used synonymous with the term “polynucleotide”. Preferably, a nucleic acid molecule is a polymer comprising or consisting of nucleotide monomers, which are covalently linked to each other by phosphodiester-bonds of a sugar/phosphate-backbone. The term “nucleic acid molecule” also encompasses modified nucleic acid molecules, such as base-modified, sugar-modified or backbone-modified etc. DNA or RNA molecules.

Open reading frame: An open reading frame (ORF) in the context of the invention may typically be a sequence of several nucleotide triplets, which may be translated into a peptide or protein. An open reading frame preferably contains a start codon, i.e. a combination of three subsequent nucleotides coding usually for the amino acid methionine (ATG), at its 5′-end and a subsequent region, which usually exhibits a length which is a multiple of 3 nucleotides. An ORF is preferably terminated by a stop-codon (e.g., TAA, TAG, TGA). Typically, this is the only stop-codon of the open reading frame. Thus, an open reading frame in the context of the present invention is preferably a nucleotide sequence, consisting of a number of nucleotides that may be divided by three, which starts with a start codon (e.g. ATG) and which preferably terminates with a stop codon (e.g., TAA, TGA, or TAG). The open reading frame may be isolated or it may be incorporated in a longer nucleic acid sequence, for example in a vector or an mRNA. An open reading frame may also be termed “protein coding region”.

Peptide: A peptide or polypeptide is typically a polymer of amino acid monomers, linked by peptide bonds. It typically contains less than 50 monomer units. Nevertheless, the term peptide is not a disclaimer for molecules having more than 50 monomer units. Long peptides are also called polypeptides, typically having between 50 and 600 monomeric units.

Pharmaceutically effective amount: A pharmaceutically effective amount in the context of the invention is typically understood to be an amount that is sufficient to induce a pharmaceutical effect, such as an immune response, altering a pathological level of an expressed peptide or protein, or substituting a lacking gene product, e.g., in case of a pathological situation.

Protein A protein typically comprises one or more peptides or polypeptides. A protein is typically folded into 3-dimensional form, which may be required for to protein to exert its biological function.

Poly(A) sequence: A poly(A) sequence, also called poly(A) tail or 3′-poly(A) tail, is typically understood to be a sequence of adenosine nucleotides, e.g., of up to about 400 adenosine nucleotides, e.g. from about 20 to about 400, preferably from about 50 to about 400, more preferably from about 50 to about 300, even more preferably from about 50 to about 250, most preferably from about 60 to about 250 adenosine nucleotides. A poly(A) sequence is typically located at the 3′ end of an mRNA. In the context of the present invention, a poly(A) sequence may be located within an mRNA or any other nucleic acid molecule, such as, e.g., in a vector, for example, in a vector serving as template for the generation of an RNA, preferably an mRNA, e.g., by transcription of the vector.

Polyadenylation: Polyadenylation is typically understood to be the addition of a poly(A) sequence to a nucleic acid molecule, such as an RNA molecule, e.g. to a premature mRNA. Polyadenylation may be induced by a so-called polyadenylation signal. This signal is preferably located within a stretch of nucleotides at the 3′-end of a nucleic acid molecule, such as an RNA molecule, to be polyadenylated. A polyadenylation signal typically comprises a hexamer consisting of adenine and uracil/thymine nucleotides, preferably the hexamer sequence AAUAAA. Other sequences, preferably hexamer sequences, are also conceivable. Polyadenylation typically occurs during processing of a pre-mRNA (also called premature-mRNA). Typically, RNA maturation (from pre-mRNA to mature mRNA) comprises the step of polyadenylation.

Restriction site: A restriction site, also termed restriction enzyme recognition site, is a nucleotide sequence recognized by a restriction enzyme. A restriction site is typically a short, preferably palindromic nucleotide sequence, e.g. a sequence comprising 4 to 8 nucleotides. A restriction site is preferably specifically recognized by a restriction enzyme. The restriction enzyme typically cleaves a nucleotide sequence comprising a restriction site at this site. In a double-stranded nucleotide sequence, such as a double-stranded DNA sequence, the restriction enzyme typically cuts both strands of the nucleotide sequence.

RNA, mRNA: RNA is the usual abbreviation for ribonucleic-acid. It is a nucleic acid molecule, i.e. a polymer consisting of nucleotides. These nucleotides are usually adenosine-monophosphate, uridine-monophosphate, guanosine-monophosphate and cytidine-monophosphate monomers which are connected to each other along a so-called backbone. The backbone is formed by phosphodiester bonds between the sugar, i.e. ribose, of a first and a phosphate moiety of a second, adjacent monomer. The specific succession of the monomers is called the RNA-sequence. Usually RNA may be obtainable by transcription of a DNA-sequence, e.g., inside a cell. In eukaryotic cells, transcription is typically performed inside the nucleus or the mitochondria. In vivo, transcription of DNA usually results in the so-called premature RNA which has to be processed into so-called messenger-RNA, usually abbreviated as mRNA. Processing of the premature RNA, e.g. in eukaryotic organisms, comprises a variety of different posttranscriptional-modifications such as splicing, 5′-capping, polyadenylation, export from the nucleus or the mitochondria and the like. The sum of these processes is also called maturation of RNA. The mature messenger RNA usually provides the nucleotide sequence that may be translated into an amino-acid sequence of a particular peptide or protein. Typically, a mature mRNA comprises a 5′-cap, a 5′-UTR, an open reading frame, a 3′-UTR and a poly(A) sequence. Aside from messenger RNA, several non-coding types of RNA exist which may be involved in regulation of transcription and/or translation.

Sequence of a nucleic acid molecule: The sequence of a nucleic acid molecule is typically understood to be the particular and individual order, i.e. the succession of its nucleotides. The sequence of a protein or peptide is typically understood to be the order, i.e. the succession of its amino acids.

Sequence identity: Two or more sequences are identical if they exhibit the same length and order of nucleotides or amino acids. The percentage of identity typically describes the extent to which two sequences are identical, i.e. it typically describes the percentage of nucleotides that correspond in their sequence position with identical nucleotides of a reference-sequence. For determination of the degree of identity, the sequences to be compared are considered to exhibit the same length, i.e. the length of the longest sequence of the sequences to be compared. This means that a first sequence consisting of 8 nucleotides is 80% identical to a second sequence consisting of 10 nucleotides comprising the first sequence. In other words, in the context of the present invention, identity of sequences preferably relates to the percentage of nucleotides of a sequence which have the same position in two or more sequences having the same length. Gaps are usually regarded as non-identical positions, irrespective of their actual position in an alignment.

Stabilized nucleic acid molecule: A stabilized nucleic acid molecule is a nucleic acid molecule, preferably a DNA or RNA molecule that is modified such, that it is more stable to disintegration or degradation, e.g., by environmental factors or enzymatic digest, such as by an exo- or endonuclease degradation, than the nucleic acid molecule without the modification. Preferably, a stabilized nucleic acid molecule in the context of the present invention is stabilized in a cell, such as a prokaryotic or eukaryotic cell, preferably in a mammalian cell, such as a human cell. The stabilization effect may also be exerted outside of cells, e.g. in a buffer solution etc., for example, in a manufacturing process for a pharmaceutical composition comprising the stabilized nucleic acid molecule.

Transfection: The term “transfection” refers to the introduction of nucleic acid molecules, such as DNA or RNA (e.g. mRNA) molecules, into cells, preferably into eukaryotic cells. In the context of the present invention, the term “transfection” encompasses any method known to the skilled person for introducing nucleic acid molecules into cells, preferably into eukaryotic cells, such as into mammalian cells. Such methods encompass, for example, electroporation, lipofection, e.g. based on cationic lipids and/or liposomes, calcium phosphate precipitation, nanoparticle based transfection, virus based transfection, or transfection based on cationic polymers, such as DEAE-dextran or polyethylenimine etc. Preferably, the introduction is non-viral.

Vaccine: A vaccine is typically understood to be a prophylactic or therapeutic material providing at least one antigen, preferably an immunogen. The antigen or immunogen may be derived from any material that is suitable for vaccination. For example, the antigen or immunogen may be derived from a pathogen, such as from bacteria or virus particles etc., or from a tumor or cancerous tissue. The antigen or immunogen stimulates the body's adaptive immune system to provide an adaptive immune response.

Vector: The term “vector” refers to a nucleic acid molecule, preferably to an artificial nucleic acid molecule. A vector in the context of the present invention is suitable for incorporating or harboring a desired nucleic acid sequence, such as a nucleic acid sequence comprising an open reading frame. Such vectors may be storage vectors, expression vectors, cloning vectors, transfer vectors etc. A storage vector is a vector, which allows the convenient storage of a nucleic acid molecule, for example, of an mRNA molecule. Thus, the vector may comprise a sequence corresponding, e.g., to a desired mRNA sequence or a part thereof, such as a sequence corresponding to the open reading frame and the 3′-UTR of an mRNA. An expression vector may be used for production of expression products such as RNA, e.g. mRNA, or peptides, polypeptides or proteins. For example, an expression vector may comprise sequences needed for transcription of a sequence stretch of the vector, such as a promoter sequence, e.g. an RNA polymerase promoter sequence. A cloning vector is typically a vector that contains a cloning site, which may be used to incorporate nucleic acid sequences into the vector. A cloning vector may be, e.g., a plasmid vector or a bacteriophage vector. A transfer vector may be a vector, which is suitable for transferring nucleic acid molecules into cells or organisms, for example, viral vectors. A vector in the context of the present invention may be, e.g., an RNA vector or a DNA vector. Preferably, a vector is a DNA molecule. Preferably, a vector in the sense of the present application comprises a cloning site, a selection marker, such as an antibiotic resistance factor, and a sequence suitable for multiplication of the vector, such as an origin of replication. Preferably, a vector in the context of the present application is a plasmid vector.

Vehicle: A vehicle is typically understood to be a material that is suitable for storing, transporting, and/or administering a compound, such as a pharmaceutically active compound. For example, it may be a physiologically acceptable liquid, which is suitable for storing, transporting, and/or administering a pharmaceutically active compound.

3′-untranslated region (3′-UTR): Generally, the term “3′-UTR” refers to a part of the artificial nucleic acid molecule, which is located 3′ (i.e. “downstream”) of an open reading frame and which is not translated into protein. Typically, a 3′-UTR is the part of an mRNA which is located between the protein coding region (open reading frame (ORF) or coding sequence (CDS)) and the poly(A) sequence of the mRNA. In the context of the invention, the term 3′-UTR may also comprise elements, which are not encoded in the template, from which an RNA is transcribed, but which are added after transcription during maturation, e.g. a poly(A) sequence. A 3′-UTR of the mRNA is not translated into an amino acid sequence. The 3′-UTR sequence is generally encoded by the gene, which is transcribed into the respective mRNA during the gene expression process. The genomic sequence is first transcribed into pre-mature mRNA, which comprises optional introns. The pre-mature mRNA is then further processed into mature mRNA in a maturation process. This maturation process comprises the steps of 5′capping, splicing the pre-mature mRNA to excise optional introns and modifications of the 3′-end, such as polyadenylation of the 3′-end of the pre-mature mRNA and optional endo-/or exonuclease cleavages etc. In the context of the present invention, a 3′-UTR corresponds to the sequence of a mature mRNA, which is located between the stop codon of the protein coding region, preferably immediately 3′ to the stop codon of the protein coding region, and the poly(A) sequence of the mRNA. The term “corresponds to” means that the 3′-UTR sequence may be an RNA sequence, such as in the mRNA sequence used for defining the 3′-UTR sequence, or a DNA sequence, which corresponds to such RNA sequence. In the context of the present invention, the term “a 3′-UTR of a gene”, such as “a 3′-UTR of a ribosomal protein gene”, is the sequence, which corresponds to the 3′-UTR of the mature mRNA derived from this gene, i.e. the mRNA obtained by transcription of the gene and maturation of the pre-mature mRNA. The term “3′-UTR of a gene” encompasses the DNA sequence and the RNA sequence (both sense and antisense strand and both mature and immature) of the 3′-UTR.

5′-untranslated region (5′-UTR): A 5′-UTR is typically understood to be a particular section of messenger RNA (mRNA). It is located 5′ of the open reading frame of the mRNA. Typically, the 5′-UTR starts with the transcriptional start site and ends one nucleotide before the start codon of the open reading frame. The 5′-UTR may comprise elements for controlling gene expression, also called regulatory elements. Such regulatory elements may be, for example, ribosomal binding sites. The 5′-UTR may be post-transcriptionally modified, for example by addition of a 5′-CAP. In the context of the present invention, a 5′-UTR corresponds to the sequence of a mature mRNA, which is located between the 5′-CAP and the start codon. Preferably, the 5′-UTR corresponds to the sequence, which extends from a nucleotide located 3′ to the 5′-CAP, preferably from the nucleotide located immediately 3′ to the 5′-CAP, to a nucleotide located 5′ to the start codon of the protein coding region, preferably to the nucleotide located immediately 5′ to the start codon of the protein coding region. The nucleotide located immediately 3′ to the 5′-CAP of a mature mRNA typically corresponds to the transcriptional start site. The term “corresponds to” means that the 5′-UTR sequence may be an RNA sequence, such as in the mRNA sequence used for defining the 5′-UTR sequence, or a DNA sequence, which corresponds to such RNA sequence. In the context of the present invention, the term “a 5′-UTR of a gene” is the sequence, which corresponds to the 5′-UTR of the mature mRNA derived from this gene, i.e. the mRNA obtained by transcription of the gene and maturation of the pre-mature mRNA. The term “5′-UTR of a gene” encompasses the DNA sequence and the RNA sequence of the 5′-UTR. By the inventive embodiments such a 5″-UTR may be provided 5′-terminal to the ORF. Its length is typically less than 500, 400, 300, 250 or less than 200 nucleotides. In other embodiments its length may be in the range of at least 10, 20, 30 or 40, preferably up to 100 or 150, nucleotides.

5′Terminal Oligopyrimidine Tract (TOP): The 5′terminal oligopyrimidine tract (TOP) is typically a stretch of pyrimidine nucleotides located in the 5′ terminal region of a nucleic acid molecule, such as the 5′ terminal region of certain mRNA molecules or the 5′ terminal region of a functional entity, e.g. the transcribed region, of certain genes. The sequence starts with a cytidine, which usually corresponds to the transcriptional start site, and is followed by a stretch of usually about 3 to 30 pyrimidine nucleotides. For example, the TOP may comprise 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 or even more nucleotides. The pyrimidine stretch and thus the 5′ TOP ends one nucleotide 5′ to the first purine nucleotide located downstream of the TOP. Messenger RNA that contains a 5′terminal oligopyrimidine tract is often referred to as TOP mRNA. Accordingly, genes that provide such messenger RNAs are referred to as TOP genes. TOP sequences have, for example, been found in genes and mRNAs encoding peptide elongation factors and ribosomal proteins.

TOP motif: In the context of the present invention, a TOP motif is a nucleic acid sequence which corresponds to a 5′TOP as defined above. Thus, a TOP motif in the context of the present invention is preferably a stretch of pyrimidine nucleotides having a length of 3-30 nucleotides. Preferably, the TOP-motif consists of at least 3 pyrimidine nucleotides, preferably at least 4 pyrimidine nucleotides, preferably at least 5 pyrimidine nucleotides, more preferably at least 6 nucleotides, more preferably at least 7 nucleotides, most preferably at least 8 pyrimidine nucleotides, wherein the stretch of pyrimidine nucleotides preferably starts at its 5′end with a cytosine nucleotide. In TOP genes and TOP mRNAs, the TOP-motif preferably starts at its 5′end with the transcriptional start site and ends one nucleotide 5′ to the first purin residue in said gene or mRNA. A TOP motif in the sense of the present invention is preferably located at the 5′ end of a sequence, which represents a 5′UTR, or at the 5′end of a sequence, which codes for a 5′UTR. Thus, preferably, a stretch of 3 or more pyrimidine nucleotides is called “TOP motif” in the sense of the present invention if this stretch is located at the 5′ end of a respective sequence, such as the artificial nucleic acid molecule, the 5′UTR element of the artificial nucleic acid molecule, or the nucleic acid sequence which is derived from the 5′UTR of a TOP gene as described herein. In other words, a stretch of 3 or more pyrimidine nucleotides, which is not located at the 5′-end of a 5′UTR or a 5′UTR element but anywhere within a 5′UTR or a 5′UTR element, is preferably not referred to as “TOP motif”.

TOP gene: TOP genes are typically characterised by the presence of a 5′ terminal oligopyrimidine tract. Furthermore, most TOP genes are characterized by a growth-associated translational regulation. However, also TOP genes with a tissue specific translational regulation are known. As defined above, the 5′UTR of a TOP gene corresponds to the sequence of a 5′UTR of a mature mRNA derived from a TOP gene, which preferably extends from the nucleotide located 3′ to the 5′-CAP to the nucleotide located 5′ to the start codon. A 5′UTR of a TOP gene typically does not comprise any start codons, preferably no upstream AUGs (uAUGs) or upstream open reading frames (uORFs). Therein, upstream AUGs and upstream open reading frames are typically understood to be AUGs and open reading frames that occur 5′ of the start codon (AUG) of the open reading frame that should be translated. The 5′UTRs of TOP genes are generally rather short. The lengths of 5′UTRs of TOP genes may vary between 20 nucleotides up to 500 nucleotides, and are typically less than about 200 nucleotides, preferably less than about 150 nucleotides, more preferably less than about 100 nucleotides. Exemplary 5′UTRs of TOP genes in the sense of the present invention are the nucleic acid sequences extending from the nucleotide at position 5 to the nucleotide located immediately 5′ to the start codon (e.g. the ATG) in the sequences according to SEQ ID Nos. 1-1363 of the patent application WO2013/143700, whose disclosure is incorporated herewith by reference. In this context, a particularly preferred fragment of a 5′UTR of a TOP gene is a 5′UTR of a TOP gene lacking the 5′TOP motif. The terms “5′UTR of a TOP gene” or “5′-TOP UTR” preferably refer to the 5′UTR of a naturally occurring TOP gene.

In a first aspect, the present invention relates to an artificial nucleic acid molecule comprising

-   -   a. at least one open reading frame (ORF); and     -   b. at least one 3′-untranslated region element (3′-UTR element)         comprising or consisting of a nucleic acid sequence which is         derived from the 3′-UTR of a ribosomal protein gene.

The term “3′-UTR element” refers to a nucleic acid sequence, which comprises or consists of a nucleic acid sequence that is derived from a 3′-UTR or from a variant of a 3′-UTR. A “3′-UTR element” preferably refers to a nucleic acid sequence which represents a 3′-UTR of an artificial nucleic acid sequence, such as an artificial mRNA, or which codes for a 3′-UTR of an artificial nucleic acid molecule. Accordingly, in the sense of the present invention, preferably, a 3′-UTR element may be the 3′-UTR of an mRNA, preferably of an artificial mRNA, or it may be the transcription template for a 3′-UTR of an mRNA. Thus, a 3′-UTR element preferably is a nucleic acid sequence, which corresponds to the 3′-UTR of an mRNA, preferably to the 3′-UTR of an artificial mRNA, such as an mRNA obtained by transcription of a genetically engineered vector construct. Preferably, a 3′-UTR element in the sense of the present invention functions as a 3′-UTR or codes for a nucleotide sequence that fulfils the function of a 3′-UTR.

The term “ribosomal protein gene” typically refers to a gene encoding a ribosomal protein. As used herein, the term refers to any ribosomal protein gene, irrespective of the species, from which it is derived. Specifically, the term refers to an eukaryotic ribosomal protein gene. Furthermore, in the context of the invention, the term “ribosomal protein gene” may also refer to a gene, which is similar to a ribosomal protein gene, either structurally or functionally. In particular, the term also comprises “ribosomal protein-like” genes, pseudogenes and genes sharing sequence or structural features, particularly in their 3′-UTR region, with a ribosomal protein gene. Preferably, the term refers to a vertebrate ribosomal protein gene, more preferably to a mammalian ribosomal protein gene, even more preferably to a primate ribosomal protein gene, in particular to a human ribosomal protein gene. Further, the term “ribosomal protein gene” also encompasses a rodent ribosomal protein gene, in particular a murine ribosomal protein gene.

Preferably, the term “ribosomal protein gene” refers to one of the aforementioned genes, which is derived from a mammalian, preferably from Homo sapiens or Mus musculus.

Preferably, the at least one open reading frame and the at least one 3′-UTR element are heterologous. The term “heterologous” in this context means that two sequence elements comprised by the artificial nucleic acid molecule, such as the open reading frame and the 3′-UTR element, are not occurring naturally (in nature) in this combination. Preferably, the 3′-UTR element is derived from a different gene than the open reading frame. For example, the ORF may be derived from a different gene than the 3′-UTR element, e.g. encoding a different protein or the same protein but of a different species etc. Preferably, the open reading frame does not code for a ribosomal protein. In a preferred embodiment, the ORF does not encode a human ribosomal protein or a plant (in particular Arabidopsis) ribosomal protein, in particular human ribosomal protein S6 (RPS6), human ribosomal protein L36a-like (RPL36AL) or Arabidopsis ribosomal protein S16 (RPS16). In a further preferred embodiment, the open reading frame (ORF) does not encode ribosomal protein S6 (RPS6), ribosomal protein L36a-like (RPL36AL) or ribosomal protein S16 (RPS16).

In specific embodiments it is preferred that the open reading frame does not code for a reporter protein, e.g., selected from the group consisting of globin proteins (particularly beta-globin), luciferase protein, GFP proteins or variants thereof, for example, variants exhibiting at least 70% sequence identity to a globin protein, a luciferase protein, or a GFP protein. In a particularly preferred embodiment, the open reading frame (ORF) does not encode a reporter gene or is not derived from a reporter gene, wherein the reporter gene is preferably not selected from group consisting of globin proteins (particularly beta-globin), luciferase protein, beta-glucuronidase (GUS) and GFP proteins or variants thereof, preferably not selected from EGFP, or variants of any of the above genes, typically exhibiting at least 70% sequence identity to any of these reporter genes, preferably to a globin protein, a luciferase protein, or a GFP protein.

Even more preferably, the 3′-UTR element is heterologous to any other element comprised in the artificial nucleic acid as defined herein. For example, if the artificial nucleic acid according to the invention comprises a 3′-UTR element from a given gene, it does preferably not comprise any other nucleic acid sequence, in particular no functional nucleic acid sequence (e.g. coding or regulatory sequence element) from the same gene, including its regulatory sequences at the 5′ and 3′ terminus of the gene's ORF. In a particularly preferred embodiment, the artificial nucleic acid molecule comprises an ORF, a 3′-UTR and a 5′-UTR, all of which are heterologous to each other, e.g. they are recombinant as each of them is derived from different genes (and their 5′ and 3′ UTR's). In another preferred embodiment, the 3′-UTR is not derived from a 3′-UTR of a viral gene or is of non-viral origin.

Preferably, the at least one 3′-UTR element is functionally linked to the ORF. This means preferably that the 3′-UTR element is associated with the ORF such that it may exert a function, such as an enhancing or stabilizing function on the expression of the encoded peptide or protein or a stabilizing function on the artificial nucleic acid molecule.

The phrase “nucleic acid sequence which is derived from the 3′-UTR of a ribosomal protein gene” preferably refers to a nucleic acid sequence, which is based on the 3′-UTR sequence of a ribosomal protein gene or on a fragment or part thereof. This phrase includes sequences corresponding to the entire 3′-UTR sequence, i.e. the full length 3′-UTR sequence of a ribosomal protein gene, and sequences corresponding to a fragment of the 3′-UTR sequence of a ribosomal protein gene. Preferably, a fragment of a 3′-UTR of a ribosomal protein gene consists of a continuous stretch of nucleotides corresponding to a continuous stretch of nucleotides in the full-length 3′-UTR of a ribosomal protein gene, which represents at least 5%, 10%, 20%, preferably at least 30%, more preferably at least 40%, more preferably at least 50%, even more preferably at least 60%, even more preferably at least 70%, even more preferably at least 80%, and most preferably at least 90% of the full-length 3′-UTR of a ribosomal protein gene. Such a fragment, in the sense of the present invention, is preferably a functional fragment as described herein. Preferably, the fragment retains a regulatory function for the translation of the ORF linked to the 3′-UTR or fragment thereof. The term “3′-UTR of a ribosomal protein gene” preferably refers to the 3′-UTR of a naturally occurring ribosomal protein gene.

The terms “variant of the 3′-UTR of a ribosomal protein gene” and “variant thereof” in the context of a 3′-UTR of a ribosomal protein gene refers to a variant of the 3′-UTR of a naturally occurring ribosomal protein gene, preferably to a variant of the 3′-UTR of a vertebrate ribosomal protein gene, more preferably to a variant of the 3′-UTR of a mammalian ribosomal protein gene, even more preferably to a variant of the 3′-UTR of a primate ribosomal protein gene, in particular a human ribosomal protein gene as described above. Such variant may be a modified 3′-UTR of a ribosomal protein gene. For example, a variant 3′-UTR may exhibit one or more nucleotide deletions, insertions, additions and/or substitutions compared to the naturally occurring 3′-UTR from which the variant is derived. Preferably, a variant of a 3′-UTR of a ribosomal protein gene is at least 40%, preferably at least 50%, more preferably at least 60%, more preferably at least 70%, even more preferably at least 80%, even more preferably at least 90%, most preferably at least 95% identical to the naturally occurring 3′-UTR the variant is derived from. Preferably, the variant is a functional variant as described herein.

The phrase “a nucleic acid sequence which is derived from a variant of the 3′-UTR of a ribosomal protein gene” preferably refers to a nucleic acid sequence which is based on a variant of the 3′-UTR sequence of a ribosomal protein gene or on a fragment or part thereof as described above. This phrase includes sequences corresponding to the entire sequence of the variant of the 3′-UTR of a ribosomal protein gene, i.e. the full length variant 3′-UTR sequence of a ribosomal protein gene, and sequences corresponding to a fragment of the variant 3′-UTR sequence of a ribosomal protein gene. Preferably, a fragment of a variant of the 3′-UTR of a ribosomal protein gene consists of a continuous stretch of nucleotides corresponding to a continuous stretch of nucleotides in the full-length variant of the 3′-UTR of a ribosomal protein gene, which represents at least 20%, preferably at least 30%, more preferably at least 40%, more preferably at least 50%, even more preferably at least 60%, even more preferably at least 70%, even more preferably at least 80%, and most preferably at least 90% of the full-length variant of the 3′-UTR of a ribosomal protein gene. Such a fragment of a variant, in the sense of the present invention, is preferably a functional fragment of a variant as described herein.

The terms “functional variant”, “functional fragment”, and “functional fragment of a variant” (also termed “functional variant fragment”) in the context of the present invention, mean that the fragment of the 3′-UTR, the variant of the 3′-UTR, or the fragment of a variant of the 3′-UTR of a ribosomal protein gene fulfils at least one, preferably more than one function of the naturally occurring 3′-UTR of a ribosomal protein gene of which the variant, the fragment, or the fragment of a variant is derived. Such function may be, for example, stabilizing mRNA and/or enhancing, stabilizing and/or prolonging protein production from an mRNA and/or increasing protein expression or total protein production from an mRNA, preferably in a mammalian cell, such as in a human cell. Preferably, the function of the 3′-UTR concerns the translation of the protein encoded by the ORF. More preferably, the function comprises enhancing translation efficiency of the ORF linked to the 3′-UTR or fragment or variant thereof. It is particularly preferred that the variant, the fragment, and the variant fragment in the context of the present invention fulfil the function of stabilizing an mRNA, preferably in a mammalian cell, such as a human cell, compared to an mRNA comprising a reference 3′-UTR or lacking a 3′-UTR, and/or the function of enhancing, stabilizing and/or prolonging protein production from an mRNA, preferably in a mammalian cell, such as in a human cell, compared to an mRNA comprising a reference 3′-UTR or lacking a 3′-UTR, and/or the function of increasing protein production from an mRNA, preferably in a mammalian cell, such as in a human cell, compared to an mRNA comprising a reference 3′-UTR or lacking a 3′-UTR. A reference 3′-UTR may be, for example, a 3′-UTR naturally occurring in combination with the ORF. Furthermore, a functional variant, a functional fragment, or a functional variant fragment of a 3′-UTR of a ribosomal protein gene preferably does not have a substantially diminishing effect on the efficiency of translation of the mRNA which comprises such variant, fragment, or variant fragment of a 3′-UTR compared to the wild type 3′-UTR from which the variant, the fragment, or the variant fragment is derived. A particularly preferred function of a “functional fragment”, a “functional variant” or a “functional fragment of a variant” of the 3′-UTR of a ribosomal protein gene in the context of the present invention is the enhancement, stabilization and/or prolongation of protein production by expression of an mRNA carrying the functional fragment, functional variant or functional fragment of a variant as described above.

Preferably, the efficiency of the one or more functions exerted by the functional variant, the functional fragment, or the functional variant fragment, such as mRNA and/or protein production stabilizing efficiency and/or the protein production increasing efficiency, is increased by at least 5%, more preferably by at least 10%, more preferably by at least 20%, more preferably by at least 30%, more preferably by at least 40%, more preferably by at least 50%, more preferably by at least 60%, even more preferably by at least 70%, even more preferably by at least 80%, most preferably by at least 90% with respect to the mRNA and/or protein production stabilizing efficiency and/or the protein production increasing efficiency exhibited by the naturally occurring 3′-UTR of a ribosomal protein gene from which the variant, the fragment or the variant fragment is derived.

In the context of the present invention, a fragment of the 3′-UTR of a ribosomal protein gene or of a variant of the 3′-UTR of a ribosomal protein gene preferably exhibits a length of at least about 3 nucleotides, preferably of at least about 5 nucleotides, more preferably of at least about 10, 15, 20, 25 or 30 nucleotides, even more preferably of at least about 50 nucleotides, most preferably of at least about 70 nucleotides. Preferably, such fragment of the 3′-UTR of a ribosomal protein gene or of a variant of the 3′-UTR of a ribosomal protein gene is a functional fragment as described above. In a preferred embodiment, the 3′-UTR of a ribosomal protein gene or a fragment or variant thereof exhibits a length of between 3 and about 500 nucleotides, preferably of between 5 and about 150 nucleotides, more preferably of between 10 and 100 nucleotides, even more preferably of between 15 and 90, most preferably of between 20 and 70.

Preferably, the at least one 3′-UTR element of the artificial nucleic acid molecule according to the present invention comprises or consists of a “functional fragment”, a “functional variant” or a “functional fragment of a variant” of the 3′-UTR of a ribosomal protein gene.

In a preferred embodiment, the at least one 3′-UTR element of the artificial nucleic acid molecule according to the present invention increases the stability of the artificial nucleic acid molecule, e.g. increases the stability of an mRNA according to the present invention, compared to a respective nucleic acid (reference nucleic acid) lacking a 3′-UTR or comprising a reference 3′-UTR, such as a 3′-UTR naturally occurring in combination with the ORF. Preferably, the at least one 3′-UTR element of the artificial nucleic acid molecule according to the present invention increases the stability of protein production from the artificial nucleic acid molecule according to the present invention, e.g. from an mRNA according to the present invention, compared to a respective nucleic acid lacking a 3′-UTR or comprising a reference 3′-UTR, such as a 3′-UTR naturally occurring in combination with the ORF. Preferably, the at least one 3′-UTR element of the artificial nucleic acid molecule according to the present invention prolongs protein production from the artificial nucleic acid molecule according to the present invention, e.g. from an mRNA according to the present invention, compared to a respective nucleic acid lacking a 3′-UTR or comprising a reference 3′-UTR, such as a 3′-UTR naturally occurring in combination with the ORF. Preferably, the at least one 3′-UTR element of the artificial nucleic acid molecule according to the present invention increases the protein expression and/or total protein production from the artificial nucleic acid molecule according to the present invention, e.g. from an mRNA according to the present invention, compared to a respective nucleic acid lacking a 3′-UTR or comprising a reference 3′-UTR, such as a 3′-UTR naturally occurring in combination with the ORF. Preferably, the at least one 3′-UTR element of the artificial nucleic acid molecule according to the present invention does not negatively influence translational efficiency of an nucleic acid compared to the translational efficiency of a respective nucleic acid lacking a 3′-UTR or comprising a reference 3′-UTR, such as a 3′-UTR naturally occurring in combination with the ORF. Even more preferably, the translation efficiency is enhanced by the 3′-UTR in comparison to the translation efficiency of the protein encoded by the respective ORF in its natural context.

The term “respective nucleic acid molecule” or “reference nucleic acid molecule” in this context means that—apart from the different 3′-UTRs—the reference nucleic acid molecule is comparable, preferably identical, to the inventive artificial nucleic acid molecule comprising the 3′-UTR element.

The term “stabilizing and/or prolonging protein production” from an artificial nucleic acid molecule such as an artificial mRNA preferably means that the protein production from the artificial nucleic acid molecule such as the artificial mRNA is stabilized and/or prolonged compared to the protein production from a reference nucleic acid molecule such as a reference mRNA, e.g. comprising a reference 3′-UTR or lacking a 3′-UTR, preferably in a mammalian expression system, such as in HeLa or HDF cells. Thus, protein produced from the artificial nucleic acid molecule such as the artificial mRNA is observable for a longer period of time than what may be seen for a protein produced from a reference nucleic acid molecule. In other words, the amount of protein produced from the artificial nucleic acid molecule such as the artificial mRNA measured over time undercuts a threshold value at a later time point than the amount of protein produced from a reference nucleic acid molecule such as a reference mRNA measured over time. Such a threshold value may be, for example, the amount of protein measured in the initial phase of expression, such as 1, 2, 3, 4, 5 or 6 hours post initiation of expression, such as post transfection of the nucleic acid molecule.

For example, the protein production from the artificial nucleic acid molecule such as the artificial mRNA—in an amount which is at least the amount observed in the initial phase of expression, such as 1, 2, 3, 4, 5, or 6 hours post initiation of expression, such as post transfection of the nucleic acid molecule—is prolonged by at least about 5 hours, preferably by at least about 10 hours, more preferably by at least about 24 hours compared to the protein production from a reference nucleic acid molecule, such as a reference mRNA, in a mammalian expression system, such as in mammalian cells, e.g. in HeLa or HDF cells. Thus, the artificial nucleic acid molecule according to the present invention preferably allows for prolonged protein production in an amount which is at least the amount observed in the initial phase of expression, such as 1, 2, 3, 4, 5, or 6 hours post initiation of expression, such as post transfection, by at least about 5 hours, preferably by at least about 10 hours, more preferably by at least about 24 hours compared to a reference nucleic acid molecule lacking a 3′-UTR or comprising a reference 3′-UTR.

In preferred embodiments, the period of protein production from the artificial nucleic acid molecule according to the present invention is extended at least 1.5 fold, preferably at least 2 fold, more preferably at least 2.5 fold compared to the protein production from a reference nucleic acid molecule lacking a 3′-UTR or comprising a reference 3′-UTR.

This effect of prolonging protein production may be determined by (i) measuring protein amounts, e.g. obtained by expression of an encoded reporter protein such as luciferase, preferably in a mammalian expression system such as in HeLa or HDF cells, over time, (ii) determining the time point at which the protein amount undercuts the amount of protein observed, e.g., at 1, 2, 3, 4, 5, or 6 hours post initiation of expression, e.g. 1, 2, 3, 4, 5, or 6 hours post transfection of the artificial nucleic acid molecule, and (iii) comparing the time point at which the protein amount undercuts the protein amount observed at 1, 2, 3, 4, 5, or 6 hours post initiation of expression to said time point determined for a nucleic acid molecule lacking a 3′-UTR or comprising a reference 3′-UTR.

Preferably, this stabilizing and/or prolonging effect on protein production is achieved, while the total amount of protein produced from the artificial nucleic acid molecule according to the present invention, e.g. within a time span of 48 or 72 hours, is at least the amount of protein produced from a reference nucleic acid molecule lacking a 3′-UTR or comprising a reference 3′-UTR, such as a 3′-UTR naturally occurring with the ORF of the artificial nucleic acid molecule. Thus, the present invention provides an artificial nucleic acid molecule which allows for prolonged and/or stabilized protein production in a mammalian expression system, such as in mammalian cells, e.g. in HeLa or HDF cells, as specified above, wherein the total amount of protein produced from said artificial nucleic acid molecule, e.g. within a time span of 48 or 72 hours, is at least the total amount of protein produced, e.g. within said time span, from a reference nucleic acid molecule lacking a 3′-UTR or comprising a reference 3′-UTR, such as a 3′-UTR naturally occurring with the ORF of the artificial nucleic acid molecule.

Thus, “stabilized protein expression” preferably means that there is more uniform protein production from the artificial nucleic acid molecule according to the present invention over a predetermined period of time, such as over 24 hours, more preferably over 48 hours, even more preferably over 72 hours, when compared to a reference nucleic acid molecule, for example, an mRNA comprising a reference 3′-UTR or lacking a 3′-UTR. Accordingly, the level of protein production, e.g. in a mammalian system, from the artificial nucleic acid molecule comprising a 3′-UTR element according to the present invention, e.g. from an mRNA according to the present invention, preferably does not drop to the extent observed for a reference nucleic acid molecule, such as a reference mRNA as described above. For example, the amount of a protein (encoded by the ORF) observed 6 hours after initiation of expression, e.g. 6 hours post transfection of the artificial nucleic acid molecule according to the present invention into a cell, such as a mammalian cell, may be comparable to the amount of protein observed 48 hours after initiation of expression, e.g. 48 hours post transfection. Thus, the ratio of the amount of protein encoded by the ORF, such as of a reporter protein, e.g., luciferase, observed at 48 hours post initiation of expression, e.g. 48 hours post transfection, to the amount of protein observed 6 hours after initiation of expression, e.g. 6 hours post transfection, is preferably at least about 0.4, more preferably at least about 0.5, more preferably at least about 0.6, even more preferably at least about 0.7. Preferably, the ratio is between about 0.4 and about 4, preferably between about 0.65 and about 3, more preferably between about 0.7 and 2 for a nucleic acid molecule according to the present invention. For a respective reference nucleic acid molecule, e.g. an mRNA comprising a reference 3′-UTR or lacking a 3′-UTR, said ratio may be, e.g. between about 0.05 and about 0.3.

Thus, the present invention provides an artificial nucleic acid molecule comprising an ORF and a 3′-UTR element as described above, wherein the ratio of the (reporter) protein amount, e.g. the amount of luciferase, observed 48 hours after initiation of expression to the (reporter) protein amount observed 6 hours after initiation of expression, preferably in a mammalian expression system, such as in mammalian cells, e.g. in HeLa cells, is preferably above about 0.4, more preferably above about 0.5, more preferably above about 0.6, even more preferably above about 0.7, e.g. between about 0.4 and about 4, preferably between about 0.65 and about 3, more preferably between about 0.7 and 2, wherein preferably the total amount of protein produced from said artificial nucleic acid molecule, e.g. within a time span of 48 hours, is at least the total amount of protein produced, e.g. within said time span, from a reference nucleic acid molecule lacking a 3′-UTR or comprising a reference 3′-UTR, such as a 3′-UTR naturally occurring with the ORF of the artificial nucleic acid molecule. In a preferred embodiment, the present invention provides an artificial nucleic acid molecule comprising an ORF and a 3′-UTR element as described above, wherein the ratio of the (reporter) protein amount, e.g. the amount of luciferase, observed 72 hours after initiation of expression to the (reporter) protein amount observed 6 hours after initiation of expression, preferably in a mammalian expression system, such as in mammalian cells, e.g. in HeLa cells, is preferably above about 0.4, more preferably above about 0.5, more preferably above about 0.6, even more preferably above about 0.7, e.g. between about 0.4 and 1.5, preferably between about 0.65 and about 1.15, more preferably between about 0.7 and 1.0, wherein preferably the total amount of protein produced from said artificial nucleic acid molecule, e.g. within a time span of 72 hours, is at least the total amount of protein produced, e.g. within said time span, from a reference nucleic acid molecule lacking a 3′-UTR or comprising a reference 3′-UTR, such as a 3′-UTR naturally occurring with the ORF of the artificial nucleic acid molecule.

“Increased protein expression” or “enhanced protein expression” in the context of the present invention preferably means an increased/enhanced protein expression at one time point after initiation of expression or an increased/enhanced total amount of expressed protein compared to the expression induced by a reference nucleic acid molecule. Thus, the protein level observed at a certain time point after initiation of expression, e.g. after transfection, of the artificial nucleic acid molecule according to the present invention, e.g. after transfection of an mRNA according to the present invention, for example, 6, 12, 24, 48 or 72 hours post transfection, is preferably higher than the protein level observed at the same time point after initiation of expression, e.g. after transfection, of a reference nucleic acid molecule, such as a reference mRNA comprising a reference 3′-UTR or lacking a 3′-UTR. In a preferred embodiment, the maximum amount of protein (as determined e.g. by protein activity or mass) expressed from the artificial nucleic acid molecule is increased with respect to the protein amount expressed from a reference nucleic acid comprising a reference 3′-UTR or lacking a 3′-UTR. Peak expression levels are preferably reached within 48 hours, more preferably within 24 hours and even more preferably within 12 hours after, for instance, transfection.

In one embodiment, “increased total protein production” or “enhanced total protein production” from an artificial nucleic acid molecule according to the invention refers to an increased/enhanced protein production over the time span, in which protein is produced from an artificial nucleic acid molecule, preferably in a mammalian expression system, such as in mammalian cells, e.g. in HeLa or HDF cells in comparison to a reference nucleic acid molecule lacking a 3′-UTR or comprising a reference 3′-UTR. According to a preferred embodiment, the cumulative amount of protein expressed over time is increased when using the artificial nucleic acid molecule according to the invention.

According to the invention, an artificial nucleic acid molecule is provided, which is characterized by increased expression of the encoded protein in comparison to a respective nucleic acid molecule lacking the at least one 3′-UTR element or comprising a reference 3′-UTR (“reference nucleic acid”) comprising a nucleic acid sequence which is derived from the 3′-UTR of a ribosomal protein gene or from a variant of the 3′-UTR of a ribosomal protein gene In order to assess the in vivo protein production by the inventive artificial nucleic acid molecule, the expression of the encoded protein is determined following injection/transfection of the inventive artificial nucleic acid molecule into target cells/tissue and compared to the protein expression induced by the reference nucleic acid. Quantitative methods for determining protein expression are known in the art (e.g. Western-Blot, FACS, ELISA, mass spectometry). Particularly useful in this context is the determination of the expression of reporter proteins like luciferase, Green fluorescent protein (GFP), or secreted alkaline phosphatase (SEAP). Thus, an artificial nucleic acid according to the invention or a reference nucleic acid is introduced into the target tissue or cell, e.g. via transfection or injection. Several hours or several days (e.g. 6, 12, 24, 48 or 72 hours) post initiation of expression or post introduction of the nucleic acid molecule, a target cell sample is collected and measured via FACS and/or lysed. Afterwards the lysates can be used to detect the expressed protein (and thus determine the efficiency of protein expression) using several methods, e.g. Western-Blot, FACS, ELISA, mass spectrometry or by fluorescence or luminescence measurement.

Therefore, if the protein expression from an artificial nucleic acid molecule according to the invention is compared to the protein expression from a reference nucleic acid molecule at a specific time point (e.g. 6, 12, 24, 48 or 72 hours post initiation of expression or post introduction of the nucleic acid molecule), both nucleic acid molecules are introduced separately into target tissue/cells, a sample from the tissue/cells is collected after a specific time point, protein lysates are prepared according to the particular protocol adjusted to the particular detection method (e.g. Western Blot, ELISA, etc. as known in the art) and the protein is detected by the chosen detection method. As an alternative to the measurement of expressed protein amounts in cell lysates—or, in addition to the measurement of protein amounts in cell lysates prior to lysis of the collected cells or using an aliquot in parallel—protein amounts may also be determined by using FACS analysis.

If the total amount of protein for a specific time period is to be measured, tissue or cells can be collected after several time points after introduction of the artificial nucleic acid molecule (e.g. 6, 12, 24, 48 and 72 hours post initiation of expression or post introduction of the nucleic acid molecule; usually from different test animals), and the protein amount per time point can be determined as explained above. In order to calculate the cumulative protein amount, a mathematical method of determining the total amount of protein can be used, e.g. the area under the curve (AUC) can be determined according to the following formula:

AUC = ∫_(a)^(b)f(x)d (x)

In order to calculate the area under the curve for total amount of protein, the integral of the equation of the expression curve from each end point (a and b) is calculated.

Thus, “total protein production” preferably refers to the area under the curve (AUC) representing protein production over time.

Said increase in stability of the artificial nucleic acid molecule, said increase in stability of protein production, said prolongation of protein production and/or said increase/enhancement in protein expression and/or total protein production is preferably determined by comparison with a respective reference nucleic acid molecule lacking a 3′-UTR, e.g. an mRNA lacking a 3′-UTR, or a reference nucleic acid molecule comprising a reference 3′-UTR, such as a 3′-UTR naturally occurring with the ORF as describe above.

The mRNA and/or protein production stabilizing effect and efficiency and/or the protein production increasing effect and efficiency of the variants, fragments and/or variant fragments of the 3′-UTR of a ribosomal protein gene as well as the mRNA and/or protein production stabilizing effect and efficiency and/or the protein production increasing effect and efficiency of the at least one 3′-UTR element of the artificial nucleic acid molecule according to the present invention may be determined by any method suitable for this purpose known to skilled person. For example, artificial mRNA molecules may be generated comprising a coding sequence/open reading frame (ORF) for a reporter protein, such as luciferase, and no 3′-UTR, a 3′-UTR derived from a naturally occurring ribosomal protein gene, a 3′-UTR derived from a reference gene (i.e., a reference 3′-UTR, such as a 3′-UTR naturally occurring with the ORF), as 3′-UTR a variant of a 3′-UTR of a ribosomal protein gene, as 3′-UTR a fragment of a naturally occurring ribosomal protein gene, or as 3′-UTR a fragment of a variant of a 3′-UTR of a ribosomal protein gene. Such mRNAs may be generated, for example, by in vitro transcription of respective vectors such as plasmid vectors, e.g. comprising a T7 promoter and a sequence encoding the respective mRNA sequences. The generated mRNA molecules may be transfected into cells by any transfection method suitable for transfecting mRNA, for example they may be electroporated into mammalian cells, such as HELA cells, and samples may be analyzed certain time points after transfection, for example, 6 hours, 24 hours, 48 hours, and 72 hours post transfection. Said samples may be analyzed for mRNA quantities and/or protein quantities by methods well known to the skilled person. For example, the quantities of reporter mRNA present in the cells at the sample time points may be determined by quantitative PCR methods. The quantities of reporter protein encoded by the respective mRNAs may be determined, e.g., by Western Blot, ELISA assays, FACS analysis or reporter assays, such as luciferase assays, depending on the reporter protein used. The effect of stabilizing protein expression and/or prolonging protein expression may be, for example, analyzed by determining the ratio of the protein level observed 48 hours post transfection and the protein level observed 6 hours post transfection. Preferably, the value of that ratio is greater than 1, i.e. the protein expression at the later time point is greater than the protein expression at the earlier time point. If the value for that ratio is lower than 1, the protein is more stable the closer said value is to 1. Such measurements may, of course, also be performed up at 72 or more hours and the ratio of the protein level observed 72 hours post transfection and the protein level observed 6 hours post transfection may be determined to determine stability of protein expression.

Such fragment preferably exhibits a length of at least about 3 nucleotides, preferably of at least about 5 nucleotides, more preferably of at least about 10, 15, 20, 25 or 30 nucleotides, even more preferably of at least about 50 nucleotides, most preferably of at least about 70 nucleotides. In a preferred embodiment, the fragment or variant thereof exhibits a length of between 3 and about 500 nucleotides, preferably of between 5 and about 150 nucleotides, more preferably of between 10 and 100 nucleotides, even more preferably of between 15 and 90, most preferably of between 20 and 70.

Preferably, said variants, fragments or variant fragments are functional variants, functional fragments, or functional variant fragments as described above, exhibiting at least one function of the nucleic acid sequence according to SEQ ID NOs:10 to 205, such as stabilization of the artificial nucleic acid molecule according to the invention, stabilizing and/or prolonging protein expression from the artificial nucleic acid molecule according to the invention, and/or increasing protein production, preferably with an efficiency of at least 40%, more preferably of at least 50%, more preferably of at least 60%, even more preferably of at least 70%, even more preferably of at least 80%, most preferably of at least 90% of the stabilizing efficiency and/or protein production increasing efficiency exhibited by an artificial nucleic acid molecule comprising the nucleic acid sequence according to SEQ ID No. 1 or SEQ ID NO. 2.

Preferably, the at least one 3′-UTR element of the artificial nucleic acid molecule according to the present invention exhibits a length of at least about 3 nucleotides, preferably of at least about 5 nucleotides, more preferably of at least about 10, 15, 20, 25 or 30 nucleotides, even more preferably of at least about 50 nucleotides, most preferably of at least about 70 nucleotides. The upper limit for the length of the 3′-UTR element may be 500 nucleotides or less, e.g. 400, 300, 200, 150 or 100 nucleotides. For other embodiments the upper limit may be chosen within the range of 50 to 100 nucleotides. For example, the fragment or variant thereof may exhibit a length of between 3 and about 500 nucleotides, preferably of between 5 and about 150 nucleotides, more preferably of between 10 and 100 nucleotides, even more preferably of between 15 and 90, most preferably of between 20 and 70.

Furthermore, the artificial nucleic acid molecule according to the present invention may comprise more than one 3′-UTR elements as described above. For example, the artificial nucleic acid molecule according to the present invention may comprise one, two, three, four or more 3′-UTR elements, wherein the individual 3′-UTR elements may be the same or they may be different. For example, the artificial nucleic acid molecule according to the present invention may comprise two essentially identical 3′-UTR elements as described above, e.g. two 3′-UTR elements comprising or consisting of a nucleic acid sequence, which is derived from the 3′-UTR of a ribosomal protein gene, such as from a sequence according to SEQ ID NO: 10 to 205, or from a fragment or variant of the 3′-UTR of a ribosomal protein gene, such as a nucleic acid sequence according to SEQ ID No. 1 or 2, functional variants thereof, functional fragments thereof, or functional variant fragments thereof as described above.

Surprisingly, the inventors found that an artificial nucleic acid molecule comprising a 3′-UTR element as described above may represent or may provide an mRNA molecule, which allows for enhanced, prolonged and/or stabilized protein production. Thus, a 3′-UTR element as described herein may improve stability of protein expression from an mRNA molecule and/or improve translational efficiency.

The artificial nucleic acid molecule according to the present invention may be RNA, such as mRNA, DNA, such as a DNA vector, or may be a modified RNA or DNA molecule. It may be provided as a double-stranded molecule having a sense strand and an anti-sense strand, for example, as a DNA molecule having a sense strand and an anti-sense strand.

The artificial nucleic acid molecule according to the present invention may further comprise optionally a 5′-UTR and/or a 5′-cap. The optional 5′-cap and/or the 5′-UTR are preferably located 5′ to the ORF within the artificial nucleic acid molecule according to the present invention.

Preferably, the artificial nucleic acid molecule according to the present invention further comprises a poly(A) sequence and/or a polyadenylation signal. Preferably, the optional poly(A) sequence is located 3′ to the at least one 3′-UTR element, preferably the optional poly(A) sequence is connected to the 3′-end of the 3′-UTR element. The connection may be direct or indirect, for example, via a stretch of 2, 4, 6, 8, 10, 20 etc. nucleotides, such as via a linker of 1-50, preferably of 1-20 nucleotides, e.g. comprising or consisting of one or more restriction sites.

In one embodiment, the optional polyadenylation signal is located downstream of the 3′ of the 3′-UTR element. Preferably, the polyadenylation signal comprises the consensus sequence NN(U/T)ANA, with N=A or U, preferably AA(U/T)AAA or A(U/T)(U/T)AAA. Such consensus sequence may be recognised by most animal and bacterial cell-systems, for example by the polyadenylation-factors, such as cleavage/polyadenylation specificity factor (CPSF) cooperating with CstF, PAP, PAB2, CFI and/or CFII. Preferably, the polyadenylation signal, preferably the consensus sequence NNUANA, is located less than about 50 nucleotides, more preferably less than about 30 bases, most preferably less than about 25 bases, for example 21 bases, downstream of the 3′-end of the 3′-UTR element.

Transcription of an artificial nucleic acid molecule according to the present invention, e.g. of an artificial DNA molecule, comprising a polyadenylation signal downstream of the 3′-UTR element will result in a premature-RNA containing the polyadenylation signal downstream of its 3′-UTR element. For example, transcription of a DNA molecule comprising a 3′-UTR element according to SEQ ID No. 1 will result in an RNA having a 3′-UTR element according to the sequence SEQ ID No. 2.

Using an appropriate transcription system will then lead to attachment of a poly(A) sequence to the premature-RNA. For example, the inventive artificial nucleic acid molecule may be a DNA molecule comprising a 3′-UTR element as described above and a polyadenylation signal, which may result in polyadenylation of an RNA upon transcription of this DNA molecule. Accordingly, a resulting RNA may comprise a combination of the inventive 3′-UTR element followed by a poly(A) sequence.

Potential transcription systems are in vitro transcription systems or cellular transcription systems etc. Accordingly, transcription of an artificial nucleic acid molecule according to the invention, e.g. transcription of an artificial nucleic acid molecule comprising an open reading frame, a 3′-UTR element and a polyadenylation-signal, may result in an mRNA molecule comprising an open reading frame, a 3′-UTR element and a poly(A) sequence.

Accordingly, the invention also provides an artificial nucleic acid molecule, which is an mRNA molecule comprising an open reading frame, a 3′-UTR element as described above and a poly(A) sequence.

In one embodiment, the invention provides an artificial nucleic acid molecule, which is an artificial DNA molecule comprising an open reading frame and a sequence according to SEQ ID No. 1 or a sequence having an identity of at least about 40% or more to SEQ ID No. 1 or a fragment thereof as described above. Furthermore, the invention provides an artificial nucleic acid molecule which is an artificial RNA molecule comprising an open reading frame and a sequence according to SEQ ID NO. 2 or a sequence having an identity of at least about 40% or more to SEQ ID No. 2 or a fragment thereof as described above.

Accordingly, the invention provides an artificial nucleic acid molecule, which may serve as a template for an RNA molecule, preferably for an mRNA molecule, which is stabilised and optimized with respect to translation efficiency. In other words, the artificial nucleic acid molecule may be a DNA, which may be used as a template for production of an mRNA. The obtainable mRNA, may, in turn, be translated for production of a desired peptide or protein encoded by the open reading frame. If the artificial nucleic acid molecule is a DNA, it may, for example, be used as a double-stranded storage form for continued and repetitive in vitro or in vivo production of mRNA.

In another embodiment, the 3′-UTR of the artificial nucleic acid molecule according to the invention does not comprise a polyadenylation signal or a poly(A) sequence. Further preferably, the artificial nucleic acid molecule according to the invention does not comprise a polyadenylation signal or a poly(A) sequence. More preferably, the 3′-UTR of the artificial nucleic acid molecule, or the inventive artificial nucleic acid molecule as such, does not comprise a polyadenylation signal, in particular it does not comprise the polyadenylation signal AAU/TAAA.

In one embodiment, the artificial nucleic acid molecule according to the present invention further comprises a poly(A) sequence. For example, a DNA molecule comprising an ORF followed by the ribosomal 3′ UTR may contain a stretch of thymidine nucleotides which can be transcribed into a poly(A) sequence in the resulting mRNA. The length of the poly(A) sequence may vary. For example, the poly(A) sequence may have a length of about 20 adenine nucleotides up to about 300 adenine nucleotides, preferably of about 40 to about 200 adenine nucleotides, more preferably from about 50 to about 100 adenine nucleotides, such as about 60, 70, 80, 90 or 100 adenine nucleotides. Most preferably, the inventive nucleic acid comprises a poly(A) sequence of about 60 to about 70 nucleotides, most preferably 64 adenine nucleotides.

For example, the artificial nucleic acid molecule according to the present invention may comprise a nucleic acid sequence corresponding to the DNA-sequence

Such artificial RNA-molecules, i.e. artificial nucleic acid molecules comprising a sequence according to SEQ ID No. 4 may also be obtainable in vitro by common methods of chemical-synthesis without being necessarily transcribed from a DNA-progenitor.

In a particularly preferred embodiment, the artificial nucleic acid molecule according to the present invention is an RNA molecule, preferably an mRNA molecule comprising in 5′-to-3′-direction an open reading frame, a 3′-UTR element as described above and a poly(A) sequence.

Preferably, the open reading frame does not code for a ribosomal protein. In a preferred embodiment, the open reading frame does not code for a ribosomal protein, from which the 3′-UTR element of the inventive artificial nucleic acid is derived, particularly not for a mammalian ribosomal protein, provided that the 3′-UTR element is identical to the 3′-UTR of a mammalian ribosomal protein gene. In some further preferred embodiments, the open reading frame does not code for RPS9 or variants thereof, provided that the 3′-UTR element is a sequence which is identical to SEQ ID No. 1 or SEQ ID No. 2.

In a preferred embodiment, the ORF does not encode human or plant, in particular Arabidopsis, ribosomal proteins, in particular does not encode human ribosomal protein S6 (RPS6), human ribosomal protein L36a-like (RPL36AL) or Arabidopsis ribosomal protein S16 (RPS16). In a further preferred embodiment, the open reading frame (ORF) does not encode ribosomal protein S6 (RPS6), ribosomal protein L36a-like (RPL36AL) or ribosomal protein S16 (RPS16) of whatever origin.

In one embodiment, the invention provides an artificial DNA molecule comprising an open reading frame, preferably an open reading frame which encodes a peptide or protein other than the ribosomal protein, from which the 3′-UTR is derived; a 3′-UTR element comprising or consisting of a sequence which has at least about 60%, preferably at least about 70%, more preferably at least about 80%, more preferably at least about 90%, even more preferably at least about 95%; even more preferably at least 99%; even more preferably 100% sequence identity to SEQ ID No. 1; and a polyadenylation signal and/or a poly(A) sequence. Furthermore, the invention provides an artificial DNA molecule comprising an open reading frame, preferably an open reading frame which encodes any peptide or protein other than the ribosomal protein, from which the 3′-UTR is derived; a 3′-UTR element comprising or consisting of a sequence, which has at least about 60%, preferably at least about 70%, more preferably at least about 80%, more preferably at least about 90%, even more preferably at least about 95%; even more preferably at least 99%; even more preferably 100% sequence identity to SEQ ID No. 3.

Furthermore, the invention provides an artificial RNA molecule, preferably an artificial mRNA molecule or an artificial viral RNA molecule, comprising an open reading frame, preferably an open reading frame which encodes a peptide or protein other than the ribosomal protein, from which the 3′-UTR is derived; a 3′-UTR element comprising or consisting of a sequence which has at least about 60%, preferably at least about 70%, more preferably at least about 80%, more preferably at least about 90%, even more preferably at least about 95%; even more preferably at least 99%; even more preferably 100% sequence identity to SEQ ID No. 2; and a polyadenylation signal and/or a poly(A) sequence.

The invention provides an artificial nucleic acid molecule, preferably an artificial mRNA, which may be characterized by enhanced stability and prolonged expression of the encoded peptide or protein. Without being bound by any theory, enhanced stability of protein expression and thus prolonged protein expression may result from reduction in degradation of the artificial nucleic acid molecule, such as an artificial mRNA molecule according to the present invention.

Accordingly, the inventive 3′-UTR element may prevent the artificial nucleic acid from degradation and decay.

In some embodiments, the artificial nucleic acid molecule may comprise a histone stem-loop in addition to the nucleic acid sequence derived from the 3′-UTR of a ribosomal protein gene. Such artificial nucleic acid molecule according to the present invention, for example, may comprise in 5′-to-3′-direction an ORF, an 3′-UTR element, an optional histone stem-loop sequence, an optional poly(A) sequence or polyadenylation signal and an optional poly(C) sequence.

In some embodiments, the artificial nucleic acid molecule comprises a 5′UTR element which comprises or consists of a nucleic acid sequence which is derived from the 5′UTR of a vertebrate TOP gene, such as a mammalian, e.g. a human TOP gene, selected from RPSA, RPS2, RPS3, RPS3A, RPS4, RPS5, RPS6, RPS7, RPS8, RPS9, RPS10, RPS11, RPS12, RPS13, RPS14, RPS15, RPS15A, RPS16, RPS17, RPS18, RPS19, RPS20, RPS21, RPS23, RPS24, RPS25, RPS26, RPS27, RPS27A, RPS28, RPS29, RPS30, RPL3, RPL4, RPL5, RPL6, RPL7, RPL7A, RPL8, RPL9, RPL10, RPL10A, RPL11, RPL12, RPL13, RPL13A, RPL14, RPL15, RPL17, RPL18, RPL18A, RPL19, RPL21, RPL22, RPL23, RPL23A, RPL24, RPL26, RPL27, RPL27A, RPL28, RPL29, RPL30, RPL31, RPL32, RPL34, RPL35, RPL35A, RPL36, RPL36A, RPL37, RPL37A, RPL38, RPL39, RPL40, RPL41, RPLP0, RPLP1, RPLP2, RPLP3, RPLP0, RPLP1, RPLP2, EEF1A1, EEF1B2, EEF1D, EEF1G, EEF2, EIF3E, EIF3F, EIF3H, EIF2S3, EIF3C, EIF3K, EIF3EIP, EIF4A2, PABPC1, HNRNPA1, TPT1, TUBB1, UBA52, NPM1, ATP5G2, GNB2L1, NME2, UQCRB or from a homolog or variant thereof, wherein preferably the 5′UTR element does not comprise a TOP-motif or the 5′TOP of said genes, and wherein optionally the 5′UTR element starts at its 5′-end with a nucleotide located at position 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 downstream of the 5′terminal oligopyrimidine tract (TOP) and wherein further optionally the 5′UTR element which is derived from a 5′UTR of a TOP gene terminates at its 3′-end with a nucleotide located at position 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 upstream of the start codon (A(U/T)G) of the gene it is derived from.

Preferably, the artificial nucleic acid molecule according to the present invention, preferably the open reading frame, is at least partially G/C modified. Thus, the inventive artificial nucleic acid molecule may be thermodynamically stabilized by modifying the G (guanosine)/C (cytidine) content of the molecule. The G/C content of the open reading frame of an artificial nucleic acid molecule according to the present invention may be increased compared to the G/C content of the open reading frame of a corresponding wild type sequence, preferably by using the degeneration of the genetic code. Thus, the encoded amino acid sequence of the artificial nucleic acid molecule is preferably not modified by the G/C modification compared to the coded amino acid sequence of the particular wild type sequence. The codons of the coding sequence or the whole artificial nucleic acid molecule, e.g. an mRNA, may therefore be varied compared to the wild type coding sequence, such that they include an increased amount of G/C nucleotides while the translated amino acid sequence is maintained. Due to the fact that several codons code for one and the same amino acid (so-called degeneration of the genetic code), it is feasible to alter codons while not altering the encoded peptide/protein sequence (so-called alternative codon usage). Hence, it is possible to specifically introduce certain codons (in exchange for the respective wild-type codons encoding the same amino acid), which are more favourable with respect to stability of RNA and/or with respect to codon usage in a subject (so-called codon optimization).

Depending on the amino acid to be encoded by the coding region of the inventive artificial nucleic acid molecule as defined herein, there are various possibilities for modification of the nucleic acid sequence, e.g. the open reading frame, compared to its wild type coding region. In the case of amino acids, which are encoded by codons which contain exclusively G or C nucleotides, no modification of the codon is necessary. Thus, the codons for Pro (CCC or CCG), Arg (CGC or CGG), Ala (GCC or GCG) and Gly (GGC or GGG) require no modification, since no A or U/T is present.

In contrast, codons which contain A and/or U/T nucleotides may be modified by substitution of other codons which code for the same amino acids but contain no A and/or U/T. For example

-   the codons for Pro can be modified from CC(U/T) or CCA to CCC or     CCG; -   the codons for Arg can be modified from CG(U/T) or CGA or AGA or AGG     to CGC or CGG; -   the codons for Ala can be modified from GC(U/T) or GCA to GCC or     GCG; -   the codons for Gly can be modified from GG(U/T) or GGA to GGC or     GGG.

In other cases, although A or (U/T) nucleotides cannot be eliminated from the codons, it is however possible to decrease the A and (U/T) content by using codons which contain a lower content of A and/or (U/T) nucleotides. Examples of these are:

-   The codons for Phe can be modified from (U/T)(U/T)(U/T) to (U/T)     (U/T)C; -   the codons for Leu can be modified from (U/T) (U/T)A, (U/T) (U/T)G,     C(U/T) (U/T) or C(U/T)A to C(U/T)C or C(U/T)G; -   the codons for Ser can be modified from (U/T)C(U/T) or (U/T)CA or     AG(U/T) to (U/T)CC, (U/T)CG or AGC; -   the codon for Tyr can be modified from (U/T)A(U/T) to (U/T)AC; -   the codon for Cys can be modified from (U/T)G(U/T) to (U/T)GC; -   the codon for His can be modified from CA(U/T) to CAC; -   the codon for Gln can be modified from CAA to CAG; -   the codons for Ile can be modified from A(U/T)(U/T) or A(U/T)A to     A(U/T)C; -   the codons for Thr can be modified from AC(U/T) or ACA to ACC or     ACG; -   the codon for Asn can be modified from AA(U/T) to AAC; -   the codon for Lys can be modified from AAA to AAG; -   the codons for Val can be modified from G(U/T)(U/T) or G(U/T)A to     G(U/T)C or G(U/T)G; -   the codon for Asp can be modified from GA(U/T) to GAC; -   the codon for Glu can be modified from GAA to GAG; -   the stop codon (U/T)AA can be modified to (U/T)AG or (U/T)GA.

In the case of the codons for Met (A(U/T)G) and Trp ((U/T)GG), on the other hand, there is no possibility of sequence modification without altering the encoded amino acid sequence.

The substitutions listed above can be used either individually or in all possible combinations to increase the G/C content of the open reading frame of the inventive artificial nucleic acid molecule as defined herein, compared to its particular wild type open reading frame (i.e. the original sequence). Thus, for example, all codons for Thr occurring in the wild type sequence can be modified to ACC (or ACG).

Preferably, the G/C content of the open reading frame of the inventive artificial nucleic acid molecule as defined herein is increased by at least 7%, more preferably by at least 15%, particularly preferably by at least 20%, compared to the G/C content of the wild type coding region without altering the encoded amino acid sequence, i.e. using the degeneracy of the genetic code. According to a specific embodiment at least 5%, 10%, 20%, 30%, 40%, 50%, 60%, more preferably at least 70%, even more preferably at least 80% and most preferably at least 90%, 95% or even 100% of the substitutable codons in the open reading frame of the inventive artificial nucleic acid molecule or a fragment, variant or derivative thereof are substituted, thereby increasing the G/C content of said open reading frame.

In this context, it is particularly preferable to increase the G/C content of the open reading frame of the inventive artificial nucleic acid molecule as defined herein, to the maximum (i.e. 100% of the substitutable codons), compared to the wild type open reading frame, without altering the encoded amino acid sequence.

Furthermore, the open reading frame is preferably at least partially codon-optimized. Codon-optimization is based on the finding that the translation efficiency may be determined by a different frequency in the occurrence of transfer RNAs (tRNAs) in cells. Thus, if so-called “rare codons” are present in the coding region of the inventive artificial nucleic acid molecule as defined herein, to an increased extent, the translation of the corresponding modified nucleic acid sequence is less efficient than in the case where codons coding for relatively “frequent” tRNAs are present.

Thus, the open reading frame of the inventive artificial nucleic acid molecule is preferably modified compared to the corresponding wild type coding region such that at least one codon of the wild type sequence which codes for a tRNA, which is relatively rare in the cell, is exchanged for a codon, which codes for a tRNA, which is comparably frequent in the cell and carries the same amino acid as the relatively rare tRNA. By this modification, the open reading frame of the inventive artificial nucleic acid molecule as defined herein, is modified such that codons, for which frequently occurring tRNAs are available may replace codons, which correspond to rare tRNAs. In other words, according to the invention, by such a modification all codons of the wild type open reading frame, which code for a rare tRNA, may be exchanged for a codon, which codes for a tRNA, which is more frequent in the cell and which carries the same amino acid as the rare tRNA. Which tRNAs occur relatively frequently in the cell and which, in contrast, occur relatively rarely is known to a person skilled in the art; cf. e.g. Akashi, Curr. Opin. Genet. Dev. 2001, 11(6): 660-666. Accordingly, preferably, the open reading frame is codon-optimized, preferably with respect to the system in which the artificial nucleic acid molecule according to the present invention is to be expressed, preferably with respect to the system in which the artificial nucleic acid molecule according to the present invention is to be translated. Preferably, the codon usage of the open reading frame is codon-optimized according to mammalian codon usage, more preferably according to human codon usage. Preferably, the open reading frame is codon-optimized and G/C-content modified.

For further improving degradation resistance, e.g. resistance to in vivo degradation by an exo- or endonuclease, and/or for further improving stability of protein expression from the artificial nucleic acid molecule according to the present invention, the artificial nucleic acid molecule may further comprise modifications, such as backbone modifications, sugar modifications and/or base modifications, e.g., lipid-modifications or the like.

Chemical Modifications:

The term “modification” as used herein with regard to the artificial nucleic acid molecule may refer to chemical modifications comprising backbone modifications as well as sugar modifications or base modifications.

In this context, the artificial nucleic acid molecule, preferably an RNA molecule, as defined herein may contain nucleotide analogues/modifications, e.g. backbone modifications, sugar modifications or base modifications.

A sugar modification in connection with the present invention is a chemical modification of the sugar of the nucleotides of the nucleic acid molecule as defined herein. Furthermore, a base modification in connection with the present invention is a chemical modification of the base moiety of the nucleotides of the nucleic acid molecule of the nucleic acid molecule. In this context, nucleotide analogues or modifications are preferably selected from nucleotide analogues which are applicable for transcription and/or translation.

Sugar Modifications:

The modified nucleosides and nucleotides, which may be incorporated into the artificial nucleic acid molecule, preferably an RNA, as described herein, can be modified in the sugar moiety. For example, the 2′ hydroxyl group (OH) of an RNA molecule can be modified or replaced with a number of different “oxy” or “deoxy” substituents. Examples of “oxy”-2′ hydroxyl group modifications include, but are not limited to, alkoxy or aryloxy (—OR, e.g., R=H, alkyl, cycloalkyl, aryl, aralkyl, heteroaryl or sugar); polyethyleneglycols (PEG), -0(CH2CH2o)nCH2CH2OR; “locked” nucleic acids (LNA) in which the 2′ hydroxyl is connected, e.g., by a methylene bridge, to the 4′ carbon of the same ribose sugar; and amino groups (—O-amino, wherein the amino group, e.g., NRR, can be alkylamino, dialkylamino, heterocyclyl, arylamino, diarylamino, heteroarylamino, or diheteroaryl amino, ethylene diamine, polyamino) or aminoalkoxy.

“Deoxy” modifications include hydrogen, amino (e.g. NH2; alkylamino, dialkylamino, heterocyclyl, arylamino, diaryl amino, heteroaryl amino, diheteroaryl amino, or amino acid); or the amino group can be attached to the sugar through a linker, wherein the linker comprises one or more of the atoms C, N, and O.

Backbone Modifications:

The phosphate backbone may further be modified in the modified nucleosides and nucleotides, which may be incorporated into the artificial nucleic acid molecule, preferably an RNA, as described herein. The phosphate groups of the backbone can be modified by replacing one or more of the oxygen atoms with a different substituent.

Examples of modified phosphate groups include, but are not limited to, phosphorothioate, phosphoroselenates, borano phosphates, borano phosphate esters, hydrogen phosphonates, phosphoroamidates, alkyl or aryl phosphonates and phosphotriesters. Phosphorodithioates have both non-linking oxygens replaced by sulfur. The phosphate linker can also be modified by the replacement of a linking oxygen with nitrogen (bridged phosphoroamidates), sulfur (bridged phosphorothioates) and carbon (bridged methylene-phosphonates).

Base Modifications:

The modified nucleosides and nucleotides, which may be incorporated into the artificial nucleic acid molecule, preferably an RNA molecule, as described herein, can further be modified in the nucleobase moiety.

In this context, it is particularly preferred that the lipid modification is present at the terminal ends of a linear RNA sequence.

Modification of the 5′-End of the Modified RNA:

According to another preferred embodiment of the invention, the artificial nucleic acid molecule, preferably an RNA molecule, as defined herein, can be modified by the addition of a so-called “5′ CAP” structure.

A 5′-cap is an entity, typically a modified nucleotide entity, which generally “caps” the 5′-end of a mature mRNA. A 5′-cap may typically be formed by a modified nucleotide, particularly by a derivative of a guanine nucleotide. Preferably, the 5′-cap is linked to the 5′-terminus via a 5′-5′-triphosphate linkage. A 5′-cap may be methylated, e.g. m7GpppN, wherein N is the terminal 5′ nucleotide of the nucleic acid carrying the 5′-cap, typically the 5′-end of an RNA. m7GpppN is the 5′-CAP structure which naturally occurs in mRNA transcribed by polymerase II and is therefore not considered as modification comprised in the modified RNA according to the invention. This means the artificial nucleic acid molecule, preferably an RNA molecule, according to the present invention may comprise a m7GpppN as 5′-CAP, but additionally the artificial nucleic acid molecule, preferably an RNA molecule, comprises at least one further modification as defined herein.

Further examples of 5′cap structures include glyceryl, inverted deoxy abasic residue (moiety), 4′,5′ methylene nucleotide, 1-(beta-D-erythrofuranosyl) nucleotide, 4′-thio nucleotide, carbocyclic nucleotide, 1,5-anhydrohexitol nucleotide, L-nucleotides, alpha-nucleotide, modified base nucleotide, threo-pentofuranosyl nucleotide, acyclic 3′,4′-seco nucleotide, acyclic 3,4-dihydroxybutyl nucleotide, acyclic 3,5 dihydroxypentyl nucleotide, 3′-3′-inverted nucleotide moiety, 3′-3′-inverted abasic moiety, 3′-2′-inverted nucleotide moiety, 3′-2′-inverted abasic moiety, 1,4-butanediol phosphate, 3′-phosphoramidate, hexylphosphate, aminohexyl phosphate, 3′-phosphate, 3′phosphorothioate, phosphorodithioate, or bridging or non-bridging methylphosphonate moiety. These modified 5′-CAP structures are regarded as at least one modification comprised in the artificial nucleic acid molecule, preferably in an RNA molecule, according to the present invention.

Particularly preferred modified 5′-CAP structures are CAP1 (methylation of the ribose of the adjacent nucleotide of m7G), CAP2 (methylation of the ribose of the 2^(nd) nucleotide downstream of the m7G), CAP3 (methylation of the ribose of the 3^(rd) nucleotide downstream of the m7G), CAP4 (methylation of the ribose of the 4^(th) nucleotide downstream of the m7G), ARCA (anti-reverse CAP analogue, modified ARCA (e.g. phosphothioate modified ARCA), inosine, N1-methyl-guanosine, 2′-fluoro-guanosine, 7-deaza-guanosine, 8-oxo-guanosine, 2-amino-guanosine, LNA-guanosine, and 2-azido-guanosine.

In a preferred embodiment, the at least one open reading frame encodes a therapeutic protein or peptide. In another embodiment, an antigen is encoded by the at least one open reading frame, such as a pathogenic antigen, a tumour antigen, an allergenic antigen or an autoimmune antigen. Therein, the administration of the artificial nucleic acid molecule encoding the antigen is used in a genetic vaccination approach against a disease involving said antigen.

In an alternative embodiment, an antibody is encoded by the at least one open reading frame of the artificial nucleic acid molecule according to the invention.

In a preferred embodiment, the artificial nucleic acid molecule encodes a protein or a peptide, which comprises a therapeutic protein or a fragment, variant or derivative thereof.

Therapeutic proteins as defined herein are peptides or proteins, which are beneficial for the treatment of any inherited or acquired disease or which improves the condition of an individual. Particularly, therapeutic proteins play an important role in the creation of therapeutic agents that could modify and repair genetic errors, destroy cancer cells or pathogen infected cells, treat immune system disorders, treat metabolic or endocrine disorders, among other functions. For instance, Erythropoietin (EPO), a protein hormone can be utilized in treating patients with erythrocyte deficiency, which is a common cause of kidney complications. Furthermore adjuvant proteins, therapeutic antibodies are encompassed by therapeutic proteins and also hormone replacement therapy which is e.g. used in the therapy of women in menopause. In more recent approaches, somatic cells of a patient are used to reprogram them into pluripotent stem cells, which replace the disputed stem cell therapy.

For a mass ratio of about 1:1 RNA/(Arg)9 an N/P ratio of about 2 can be calculated. When exemplarily calculated for protamine (molecular weight about 4250 g/mol, 21 nitrogen atoms, when protamine from salmon is used) with a mass ratio of about 2:1 with 2 μg RNA, 6 nmol phosphate are to be calculated for the RNA; 1 μg protamine contains about 235 pmol protamine molecules and thus 235×21=4935 pmol basic nitrogen atoms=4.9 nmol nitrogen atoms. For a mass ratio of about 2:1 RNA/protamine an N/P ratio of about 0.81 can be calculated. For a mass ratio of about 8:1 RNA/protamine an N/P ratio of about 0.2 can be calculated. In the context of the present invention, an N/P-ratio is preferably in the range of about 0.1-10, preferably in a range of about 0.3-4 and most preferably in a range of about 0.5-2 or 0.7-2 regarding the ratio of nucleic acid:peptide in the complex, and most preferably in the range of about 0.7-1.5.

Patent application WO2010/037539, the disclosure of which is incorporated herein by reference, describes an immunostimulatory composition and methods for the preparation of an immunostimulatory composition. Accordingly, in a preferred embodiment of the invention, the composition is obtained in two separate steps in order to obtain both, an efficient immunostimulatory effect and efficient translation of the artificial nucleic acid molecule according to the invention. Therein, a so called “adjuvant component” is prepared by complexing —in a first step—the artificial nucleic acid molecule or vector, preferably an RNA, of the adjuvant component with a cationic or polycationic compound in a specific ratio to form a stable complex. In this context, it is important, that no free cationic or polycationic compound or only a negligibly small amount remains in the adjuvant component after complexing the nucleic acid. Accordingly, the ratio of the nucleic acid and the cationic or polycationic compound in the adjuvant component is typically selected in a range that the nucleic acid is entirely complexed and no free cationic or polycationic compound or only a neclectably small amount remains in the composition. Preferably the ratio of the adjuvant component, i.e. the ratio of the nucleic acid to the cationic or polycationic compound is selected from a range of about 6:1 (w/w) to about 0.25:1 (w/w), more preferably from about 5:1 (w/w) to about 0.5:1 (w/w), even more preferably of about 4:1 (w/w) to about 1:1 (w/w) or of about 3:1 (w/w) to about 1:1 (w/w), and most preferably a ratio of about 3:1 (w/w) to about 2:1 (w/w).

According to a preferred embodiment, the artificial nucleic acid molecule or vector, preferably an RNA molecule, according to the invention is added in a second step to the complexed nucleic acid molecule, preferably an RNA, of the adjuvant component in order to form the (immunostimulatory) composition of the invention. Therein, the artificial acid molecule or vector, preferably an RNA, of the invention is added as free nucleic acid, i.e. nucleic acid, which is not complexed by other compounds. Prior to addition, the free artificial nucleic acid molecule or vector is not complexed and will preferably not undergo any detectable or significant complexation reaction upon the addition of the adjuvant component.

The pharmaceutical composition according to the present invention preferably comprises a “safe and effective amount” of the components of the pharmaceutical composition, particularly of the inventive artificial nucleic acid molecule, the vector and/or the cells as defined herein. As used herein, a “safe and effective amount” means an amount sufficient to significantly induce a positive modification of a disease or disorder as defined herein. At the same time, however, a “safe and effective amount” preferably avoids serious side-effects and permits a sensible relationship between advantage and risk. The determination of these limits typically lies within the scope of sensible medical judgment.

In a further aspect, the present invention provides the artificial nucleic acid molecule according to the present invention, the vector according to the present invention, the cell according to the present invention, or the pharmaceutical composition according to the present invention for use as a medicament, for example, as vaccine (in genetic vaccination) or in gene therapy.

The artificial nucleic acid molecule according to the present invention, the vector according to the present invention, the cell according to the present invention, or the pharmaceutical composition according to the present invention are particularly suitable for any medical application which makes use of the therapeutic action or effect of peptides, polypeptides or proteins, or where supplementation of a particular peptide or protein is needed. Thus, the present invention provides the artificial nucleic acid molecule according to the present invention, the vector according to the present invention, the cell according to the present invention, or the pharmaceutical composition according to the present invention for use in the treatment or prevention of diseases or disorders amenable to treatment by the therapeutic action or effect of peptides, polypeptides or proteins or amenable to treatment by supplementation of a particular peptide, polypeptide or protein. For example, the artificial nucleic acid molecule according to the present invention, the vector according to the present invention, the cell according to the present invention, or the pharmaceutical composition according to the present invention may be used for the treatment or prevention of genetic diseases, autoimmune diseases, cancerous or tumour-related diseases, infectious diseases, chronic diseases or the like, e.g., by genetic vaccination or gene therapy.

In particular, such therapeutic treatments which benefit from a stable and prolonged presence of therapeutic peptides, polypeptides or proteins in a subject to be treated are especially suitable as medical application in the context of the present invention, since the inventive 3′-UTR element provides for a stable and prolonged expression of the encoded peptide or protein of the inventive artificial nucleic acid molecule or vector. Thus, a particularly suitable medical application for the artificial nucleic acid molecule according to the present invention, the vector according to the present invention, the cell according to the present invention, or the pharmaceutical composition according to the present invention is vaccination. Thus, the present invention provides the artificial nucleic acid molecule according to the present invention, the vector according to the present invention, the cell according to the present invention, or the pharmaceutical composition according to the present invention for vaccination of a subject, preferably a mammalian subject, more preferably a human subject. Preferred vaccination treatments are vaccination against infectious diseases, such as bacterial, protozoal or viral infections, and anti-tumour-vaccination. Such vaccination treatments may be prophylactic or therapeutic.

Depending on the disease to be treated or prevented, the ORF may be selected. For example, the open reading frame may code for a protein that has to be supplied to a patient suffering from total lack or at least partial loss of function of a protein, such as a patient suffering from a genetic disease. Additionally the open reading frame may be chosen from an ORF coding for a peptide or protein, which beneficially influences a disease or the condition of a subject. Furthermore, the open reading frame may code for a peptide or protein which effects down-regulation of a pathological overproduction of a natural peptide or protein or elimination of cells expressing pathologically a protein or peptide. Such lack, loss of function or overproduction may, e.g., occur in the context of tumour and neoplasia, autoimmune diseases, allergies, infections, chronic diseases or the like. Furthermore, the open reading frame may code for an antigen or immunogen, e.g. for an epitope of a pathogen or for a tumour antigen. Thus, in preferred embodiments, the artificial nucleic acid molecule or the vector according to the present invention comprises an ORF encoding an amino acid sequence comprising or consisting of an antigen or immunogen, e.g. an epitope of a pathogen or a tumour-associated antigen, a 3′-UTR element as described above, and optional further components, such as a poly(A) sequence etc.

In the context of medical application, in particular, in the context of vaccination, it is preferred that the artificial nucleic acid molecule according to the present invention is RNA, preferably mRNA, since DNA harbours the risk of eliciting an anti-DNA immune response and tends to insert into genomic DNA. However, in some embodiments, for example, if a viral delivery vehicle, such as an adenoviral delivery vehicle is used for delivery of the artificial nucleic acid molecule or the vector according to the present invention, e.g., in the context of gene therapeutic treatments, it may be desirable that the artificial nucleic acid molecule or the vector is a DNA molecule.

EXAMPLES

1. Preparation of DNA-templates

A vector for in vitro transcription was constructed containing a T7 promoter and a GC-enriched sequence coding for Photinus pyralis luciferase (PpLuc(GC)). The 5′ untranslated region (5′-UTR) of ribosomal protein Large 32 was inserted 5′ of PpLuc(GC). An A64 poly(A) sequence, followed by C30 and a histone stem-loop sequence, was inserted 3′ of PpLuc(GC). The histone stem-loop sequence was followed by a restriction site used for linearization of the vector before in vitro transcription. mRNA obtained from this vector accordingly by in vitro transcription is designated as “rpl32-PpLuc(GC)-A64-C30-histoneSL”.

This vector was modified to include untranslated sequences 3′ of the open reading frame (3′-UTR). In summary, vectors comprising the following mRNA encoding sequences have been generated (some of the mRNA encoding sequences are depicted as examples in FIGS. 1 to 3):

-   rpl32-PpLuc(GC)-A64-C30-histoneSL (SEQ ID NO:8, FIG. 1) -   rpl32-PpLuc(GC)-ag-A64-C30-histoneSL (SEQ ID NO:9, FIG. 2) -   rpl32-PpLuc(GC)-rps9-A64-C30-histoneSL (SEQ ID NO:7, FIG. 3) -   rpl32-PpLuc(GC)-rps21-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps29-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps9-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps27-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps28-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps19-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl35a-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl13-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl36-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl23a-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl23-A64-C30-histoneSL -   rpl32-PpLuc(GC)-uba52-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl2211-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl36a-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps4x-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl27-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl3-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps23-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps13-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl26-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps17-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps18-A64-C30-histoneSL -   rpl32-PpLuc(GC)-Fau-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rps13-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl11-A64-C30-histoneSL -   rpl32-PpLuc(GC)-rpl38-A64-C30-histoneSL     2. In vitro Transcription

The DNA-template according to Example 1 was linearized and transcribed in vitro using T7-RNA polymerase. The DNA template was then digested by DNase-treatment. mRNA transcripts contained a 5′-CAP structure obtained by adding an excess of N7-Methyl-Guanosine-5′-Triphosphate-5′-Guanosine to the transcription reaction. mRNA thus obtained was purified and resuspended in water.

3. Luciferase Expression by mRNA Lipofection

Human dermal fibroblasts (HDF) or HeLa cells were seeded in 24 well plates three days before transfection at a density of 3×10⁴ cells per well in medium (RPMI 1640 medium with L-glutamine and 25 mM Hepes (Lonza, Basel, Switzerland) to which 10% FCS, 1% Pen/Strep, 1% Glutamine were added). Immediately before lipofection, cells were washed in Opti-MEM. Cells were lipofected with 25 ng of PpLuc-encoding mRNA per well complexed with Lipofectamine2000. mRNA coding for Renilla reniformis luciferase (RrLuc) was transfected together with PpLuc mRNA to control for transfection efficiency (2.5 ng of RrLuc mRNA per well). 90 minutes after start of transfection, Opti-MEM was exchanged for medium. 6, 24, 48, and 72 hours after transfection, medium was aspirated and cells were lysed in 100 μl of lysis buffer (Passive Lysis Buffer, Promega). Lysates were stored at −80° C. until luciferase activity was measured.

4. Luciferase Measurement

Luciferase activity was measured as relative light units (RLU) in a Hidex Chameleon plate reader. PpLuc activity was measured at 2 seconds measuring time using 20 μl of lysate and 50 μl of luciferin buffer (Beetle-Juice, PJK GmbH). RrLuc activity was measured at 2 seconds measuring time using 20 μl of lysate and 50 μl of coelenterazin buffer (Renilla-Juice, PJK GmbH).

5. Results

5.1 the 3′-UTR of Ribosomal Protein Genes Increases Protein Expression

To investigate the effect of the 3′-UTR of ribosomal protein genes on protein expression from mRNA, mRNAs with different UTRs were synthesized: mRNAs either lacked a 3′-UTR, or contained the center, α-complex-binding portion of the 3′-UTR of human α-globin (ag), or contained the 3′-UTR of human ribosomal protein Small 9 (rps9). Luciferase-encoding mRNAs were transfected into human dermal fibroblasts (HDF). Luciferase levels were measured at 6, 24, 48, and 72 hours after transfection. From these data, total protein expressed from 0 to 72 hours was calculated as the area under the curve (AUC) (see following Table 1 and FIG. 4).
